When you think of an aquarium it is very easy to notice the fish, the plants, the decorations and even the tank, and end up ignoring what is probably one of the most important parts of the whole aquarium set up which is the aquarium substrate.

The substrate is an essential part of the whole tank eco-system. The gravel, or sand that lies at the bottom of the tank forms an important part of the whole system and helps to provide a healthy environment for your plants and fish.

It serves several purposes. Obviously it looks decorative and finishes off the bottom of the tank nicely, but it also helps in a lot of other ways, providing a haven for the beneficial bacteria that will help with the water quality.

The type of tank that you have and what is in it will vary the type of substrate that you need. If you have decided on a tank that simply contains fish and no plants then you will only need about two inches of substrate.

The substrate could be fine sand or gravel but do make sure that it is suitable for any bottom feeders which prefer a fine gravel.

Too much substrate can cause problems of its own. If the substrate is too deep it will not get oxygenated very well and will end up creating a home for bad bacteria that will feed on left over food and create pollution in the tank. The problem is that as the substrate becomes compacted and food starts to build up in this layer it creates hydrogen sulphide. This builds up in the substrate and gets released when the substrate is disturbed causing a sudden increase in pollutants in the tank and possible health problems for the fish.

If you are planning a planted aquarium then the choice of substrate is probably one of the most important decisions that you are likely to make.

The type of substrate that you use must not only suit your fish but must also provide essential nutrients for the roots of growing plants.

With a planted aquarium the substrate will have two distinct layers. The base layer will be made up of a nutrient rich substrate such as Vermiculite which will slowly release nutrients over time. This layer needs to be a good two inches deep to allow for the plant roots.

Cover this layer with the desired substrate of gravel or sand. This is what will give your tank its final appearance and is also the substrate that the fish will come in contact with so the decision is really on sand or gravel and then fine or coarse gravel. This will give you the look that you want to achieve and keep your fish happy in their environment.

Saltwater aquarium owners will eventually need to control phosphate levels in their aquariums as the aquarium matures. Phosphate is a nutrient found in aquariums that feeds algae and inhibits calcification of invertebrates and corals.

Phosphate control can help to reduce the amount of algae that grows in an aquarium and will maximize coral growth in saltwater aquariums.

Many aquarium owners might not fully understand the benefits of phosphate control, and therefore might not practice it in their normal aquarium maintenance activities. If you have an established saltwater aquarium that is starting to have regular problems with nuisance algae growth, it’s probably time to start making a conscious effort to control phosphate levels.

Preventing High Phosphate Levels

The first step in battling phosphate levels in an aquarium is to try to prevent the amount of phosphates that are in the aquarium in the first place.

Using purified water that has gone through the process of reverse osmosis is the first step you should take. Buy a reverse osmosis water purifier and use it to purify all water that you will be putting in your aquarium.

If you do not want to buy or utilize a reverse osmosis water purifier you should find some place where you can purchase purified water. Grocery stores or maybe even pet stores (that sell fish) should be able to provide you with a source to purchase purified water.

Reducing High Phosphate Levels

If you already have high phosphate levels in your aquarium, simply switching over to purified water probably won’t help much. The rate at which you add new water to your mature aquarium will not allow you to fully swap in purified water over a short period of time.

You will need to use phosphate removal media in your aquarium to filter out all the phosphates. There are several types of phosphate removal media available from aquarium supply dealers. Take a look online at any aquarium supply dealer and you should be able to easily find some phosphate removal media. It usually is lumped in the same category as other chemical removal media such as activated carbon.

When purchasing phosphate removal media be sure to check the specifications of the brand you are using. The media may behave differently from brand to brand. Some phosphate removal media will require that you remove or replace it within days to prevent leaching of the phosphates back into the aquarium water. Other phosphate media may not need to be replaced as soon, if at all.

Implementing Phosphate Removal Media

Phosphate removal media can be implemented into your aquarium in different ways.

The first method would be to buy and install a phosphate reactor. A phosphate reactor is simply a chamber that sits within the water filtration flow of your aquarium and has an intake and outtake. The chamber is filled with phosphate removal media, which the aquarium water will flow through continuously. Phosphate reactors can be hooked up in the existing water flow plumbing of your aquarium. You can also usually hook up a separate powerhead intake and outtake into your aquarium if needed which will allow you to run the reactor independent of your other aquarium filtration.

A second method would be to buy some mesh media bags and use your current sump filter or canister filter. Fill the mesh bags with phosphate removal media and place them inside your canister filter or sump filter. The mesh bags will prevent the pieces of the media from getting all over the place in your filtration system and will make maintenance and implementation of the media much more easy to handle. The media will then be in the main water flow of your aquarium filtration system.

Once you have implemented phosphate prevention and removal techniques for a period of time, you should notice a decrease in the amount of nuisance algae in you aquarium. You may not need to clean your aquarium as often and your aquarium water quality will be improved.

Here are those practical tips :

1.Selection Based on Fish Types/Characters.

Ornamental fish you keep  should be well selected . This selection will guarantee the existence of aquarium dwellers to make them  live in a suitable environment. Some fish belong to sociable fish which means  they can live with fish of the same types and/or with other species in the same tank. Other fish live solitarily and tend to fight company which  live .

Other fish, although they do not belong to  predator and/or solitaire types, but they tend to be superior to others and this difference may create a killing field for inferior fish. This is also another factor that needs your attention  in selecting fish living in the same aquarium.

You can ask the fish seller about this fish selection  before you decide which fish to buy.

Some examples of ornamental fish which are normally  kept in  aquarium are :

Sociable fish, they can be kept collectively :

Black tetra, Black phatom tetra, Black widow tetra, Cardinal tetra,

tiger barb (Barbus tetrazona)-at least 5 fish in one tank in order not too aggressive to other fish.

Guppy (Poecilia reticulata)

Corydeoras (panda catfish).

Discus (Symphysodon discus)

Predator Fish which live solitarily  :

Flower horn fish (Amphilophus sp)

Cichlasoma sp (of family Cichlidae).

Arowana (Schleropages formosus)

Although we are talking about fish but like a saying says : “Birds of a feather flock together” you should keep different fish in one aquarium based on  similarity in their characters above.

2. Water Quality .

Water quality plays an essential role in fish life. About 90% of fish survival is determined by water quality which provides sufficient oxygen, normal pH (around 6.8-7.5), no dangerous chemicals (like methan produced by excessive food in water), etc.

Make sure that water circulation in the tank runs well and if necessary you can get more oxygen supply using a bubble pump. I don’t use any bubble pumps for my tank but keep the water circulation works properly instead and it successfully keep my fish live well so far.

3. Food.

Fish need food to live but its availability in water musn’t be excessive since it will make another problem in fish environment. Fish food contains protein and  If excessive food remains in the water for sometime, it will make deposits at the bottom and gradually produces methan gas which is poisonous to the fish and makes the water acid.

Feed your fish with enough amount  of food. You know the right amount they need when you feed them that there is no leftover which  sinks at the bottom.

Don’t worry about your fish being in short of food after you feed them if you can maintain the water ideally. As mentioned above water quality is more important for fish survival than the availability of food. Fish can survive in your tank for one week without supply of food as long as they live in quality water but they ‘ll die soon if they live with abundant  food but in bad water quality.

Don’t change the food type abruptly since this condition will stress your ornamental fish. Be consistent with one brand of food which your fish has been familiar. Different food brand may contain different composition and this may also cause interference to fish .

If you eventually  have to change the food type with other brand since you can’t find the same brand at the store anymore, try to mix it with the old type so the fish won’t experience a sudden/extreme change in their food consumption. I recommend that you buy some packs  of the same brand at one time to anticipate this condition so that you don’t have to change the food types too often.

4. Ornamental Plants.

My experience says that only small fish can live with alive ornamental plants but not the big, carnivorous ones. So if you want to grow natural ornamental plants in your tank together with ornamental fish you can consider Tetra (there are some species of this kind), Tiger barb, Guppy and Corydeoras.

You certainly need more equipment to be installed  like CO2 tank, ultraviolet lamp needed by green plants to grow healthily.

5. Fish Easily Breed in Aquarium.

If you want fish which are easily bread in your aquarium then Guppy (Poecilia reticulata) should be considered. This small and colorful fish are not only easy to be kept but also fast to breed. What they need to have for their breeding environment are hiding places to keep their eggs and young offspring, number of population (should not be too dense), the absence of predators, and healthy water.

From Latin where it comes from, aquarium is a compound word made of “aqua” (which means water) and “rium” (meaning building). Basically, the literal meaning of aquarium is “water building”. As such, freshwater aquarium is a water building designed to house fresh water fish. Finally, freshwater aquarium information is everything there is to know about keeping freshwater fish – your fish pets, your aquarium and its related equipments for operations and maintenance and more.

For the new fish-keeping hobbyists who want to start a freshwater aquarium, these are some of the general guidelines on what to remember, what to prepare and what to expect.

You will have to discover some of the details later after you finally put everything in place and having your freshwater aquarium already up and running.

First Reminders

Before buying your aquarium, the first order of the day is to consider your fish and their required future care and maintenance. Next would be on the side of economics.

Buy your aquarium and accessories at your favorite local store. Whatever you gain in mail order buys is usually wiped out by huge shipping and insurance costs.

Aquarium Tanks

Buy the biggest tank your budget will allow. Your pets will have better oxygen absorption. Small aquariums loses heat fast if the heater fails, and the water quality goes down just as fast if the filter falters.

10 gallons is the smallest you should settle for your tank, if you want to ensure a stable environment for your pets. Smaller aquariums will become easily crowded. You will have a hard time putting your plants in a small tank.

Go for tanks that are short in height and long in body. The bigger surface area is good for air exchange and there is more swimming space for your aquatic wards.

Unless they have already come up with scratch-proof acrylic tanks, stick to glass, even if they are definitely heavier than the acrylic models.

]]>

Aquarium Shape

Odd-shaped tanks look striking, but it falls short on the air exchange department. If it is tall and thin, the surface area cannot sustain the needed air exchange.

Putting in the lights, the hood and other accessories can be a pain, too. Cleaning odd-shaped aquarium tanks is definitely a chore.

Fish Capacity

This is the maximum number of fish that can fit in your tank. (You might want to get a very large fish tank so when the fish get bigger they won;t crowd each other which causes stress for them.) Buy enough number of fish in relation to their final adult size and the size of the tank.

Tank Lids

It is a toss-up between plastic and glass covers. Glass is easier to clean, covers tighter, and lets more light get in.

Plastic covers costs less, weigh less and do not break easily. Either one does not make much difference except what you think of it. Lights

Usually, lights are packaged with the lid. But you have the choice to buy lights separately. They can be incandescent, halogen, fluorescent, mercury vapor and metal halide.

Fluorescent lights cost less, and is much cooler.

Filtration

The filtration system is one critical piece of aquarium equipment. There are a number of models and styles available in the market.

The biowheeel type had been proven reliable in its filtration capability. Be aware, however, that the size of the filter should match the size of the tank.

The filter rate is how to measure the filters abiity to filter the water known as its gauge. A good one should manage to filter a tank at least four times in an hour. (A 20-gallon tank should have a filter with at least 80 gallons of flow rate per hour.Get a filter whose rating is higher whenever you are using a filter that is borderline good for your tank.

Heater

Most aquarium heaters usually come as hang-on-the-tank or submersible types. They may have a numerical setting or a simple up and down slider.

The submersible with a numerical setting is better, even if it costs more. Regarding the size, the wattage to use is 5 watts/gallon (for smaller tanks) and 3 watts/gallon (for bigger tanks).

Thermometer

The best ones are those liquid crystal stick-on types. They are inexpensive, easy to read and generally accurate enough.

Substrate

This would generally be small and smooth dark gravel. You should have one pound of rock or gravel to every one pound of water or somewhere in that comparison.

Nets

Get a medium-sized, good-quality net. Get a pair. It is easier to catch fish using two nets.

Water Conditioner

For safety, have the aquarium water aged or de-chlorinated before putting in the fish. Choose a product that will take car of the chlorine, ammonia and heavy metals.

Test Kits

The testing of water is crucial in a newly set-up tank. For newcomers, it is wise to be always ready with Ammonia, Nitrite and pH kits. Old aquarium owners should already have these kits.

Siphon

The siphon tool is needed to vacuum the gravel and also used in doing water changes. The better model is the type that uses the tap run models (they use water pressure from the tap to run the siphon).

Algae Scrubber

A medium-sized algae pad is an important tool for maintenance. (Algae will eventually grow in your tank.) Get a pad now and be prepared ahead of time.

Last Words

Generally, the most important factor in successful fish keeping is the stability of the environment. In considering all of the enumerated freshwater aquarium information above, keep in mind the stability of the environment. This will allow your fish to thrive and be happy in the new home and you to be happy- in your old home!

Setting up a saltwater aquarium can be quite difficult for a beginner. Here’s a simple guide to get you started.

More and more people are starting to pick up the hobby of maintaining saltwater aquariums. They are drawn to its more natural look, colorful and wide variety of marine life.

Freshwater fish are generally collected from streams, rivers, lakes and ponds while saltwater fish are found in seas and oceans. Saltwater life has a stable environment that they cannot easily adapt to the major changes on temperature or water chemistry.

Marine fish are taken from the wild, such that shipping and handling can be risky. This is the main reason that this hobby is more expensive than maintaining freshwater fish.

To start this hobby, buy the very basic equipment enough to get you started for the meantime. Undergravels will not be very important for a while. Get a good tank with power filters, deluxe heaters and airstones. Additional accessories include crushed corals or special gravel, a hydrometer and some sea salt mix.

Some of the saltwater fish you might consider getting are angel, anthias, batfish, basslet, blenny, cardinal, butterfly, clown, damsel, drumfish, filefish, eels, goatfish and goby.

You can also put invertebrates like a coral, anemone, gorgonian, feather duster, crab, lobster and jelly fish.

The size of the aquarium really doesn’t matter but it is better to have a large tank. This is easier to chemically balance and make it more compatible with fish. If you are quite on a budget, get a medium sized tank but be sure to be complete with all the necessary basic equipment.

When starting out, understand the basics of fish compatibility. When two kinds of fish are less related, they are more likely to get along. Any type of fish that can fit into the mouth of another fish is more likely to end up gobbled. To know more about these, research about aquarium literature.

Most hobbyists prefer a combined selection of invertebrates and fish in their aquarium. Although it is more natural to look at this way, it is also a more complicated setup. This phenomenon called Saltwater Ich can end up killing the invertebrates. Since the cell structures of invertebrates and parasites are similar, the chemical reactions are also similar.

When medicating your tank from Saltwater Ich, which usually lasts up to 4 weeks, hobbyists are forced to either sacrifice their invertebrates or their fish. The invertebrates are moved to another tank. The fish, on the other hand, runs the risk of ineffective treatment.

Taking a closer look, these saltwater invertebrates are actually carriers of the Ich problem. Since an appropriate treatment has not been finalized, most suppliers do not guarantee that their invertebrates are parasite-free.For novice hobbyists, it is best that you initially weigh the risks when having a mixed collection. It is noted that quarantine tanks and freshwater dips can actually reduce the chances that new specimens can introduce such disease to their established new habitat. For starters, you can opt to place a small number of fish for the meantime.

You can rightly say that your freshwater aquarium filter is the most important part of your fish tank; it’s the one that will maintain a clean and balanced environment so that fish can live. When cleaning out your tank, it’s most important to clean out the filter, but it’s usually not clear, especially to beginners how to go about this. This article is a guide on what you should do and why, so that you can get your filters clean without harming your fish.

There are different kinds of freshwater aquarium filters and they are usually designed to do different jobs in the fish tank, and according to the kind of fish tank in question. Many filters will do all 3 steps of filtration – mechanical, biological and chemical so you’ll not have to install 3 separate ones.

For beginners, especially with smaller tanks, an under-gravel filter is a good one to start with. It sits under the gravel in the tank and requires little maintenance. You will only need an under-gravel filter vacuum to siphon off bits and pieces that are floating around the gravel, but other than that, there isn’t much to be done. You must ensure though that you do a thorough job; any bits left behind will eventually cause your tank environment to go out of balance.

In larger aquariums though, especially those that are heavily planted, you need more than an under-gravel filter. An under-gravel filter will cause the gravel to be raised and there will be too much water movement meaning that plants never get to root properly. It will also cause air bubbles to trap and these could be toxic when they eventually pop.

Even in a small aquarium, if you have live plants, it’s a good idea to install an internal freshwater aquarium filter to avoid these 2 problems. They are not very expensive and they will save you the trouble of having to worry about your plants or trapped gases.

An internal (even external) freshwater aquarium filter needs to be cleaned once every 4 weeks, or sooner if you notice that they are clogging. This is where most beginners will have a problem, but without any ill intention. They will use hot water and then get surprised when their fish die after all that hard work!

Hot water will make a filter useless, or even dangerous for your fish. To understand why, refer back to your knowledge of the 3 filtration steps, mechanical, biological and chemical. Biological filtration is the most important because it’s the one that’s responsible for putting friendly bacteria that create a favourable environment for your fish. The bacteria are usually caught in the sponge and will be released once again into the tank when the sponge is replaced after cleaning.

What happens when you use hot water on your freshwater aquarium filter? You kill off all the bacteria, and then replace the sponge and your water is flat. There are no micro-organisms in it to provide a balanced environment and soon, you notice that your fish are sluggish and they eventually die. It’s because breakdown of compounds is not happening – there are no bacteria to aid in this. Ammonia (especially toxic) is one of the toxins that won’t break down without these friendly bacteria. Nitrites as well will not convert to nitrates and the eventual high doses will start to affect the fish. The tank will repopulate with the necessary bacteria after some time, but it may be too late by then.

So how should you clean a freshwater aquarium filter? Use cold water every 3-4 weeks. Never use soap – if you have to use anything, salt or bicarbonate of soda will do, and only in small amounts. You must not use soap on any part of your fish tank – it contains acids that will kill of your fish.

If you have many fish, clean a bit more frequently because waste accumulates faster. Disconnect the filter from the socket and take it out of the tank. Remove the cabinet that holds the filter to expose its inside and put it in a bucket. Rinse the inside in room temperature water. You’ll know its clean when the water running off it becomes clear. Don’t get it too clear though – you want to leave some “dirt” behind to repopulate the tank. Wash the rest of the filter (cabinet, piping); put everything back together and freshwater aquarium filter is good to go into the tank again.

As one’s interest and knowledge in aquarium keeping grows it is natural to want to step up to a larger tank.  One very popular mid/larger sized aquarium is the 55 gallon tank.  The larger tank really opens up a lot of wonderful possibilities to explore.  Here are a few themes and ideas of fish for a 55 gallon freshwater aquarium to get you started.

– African cichlids are some of the most colorful and interesting freshwater fish around.  They can be kept in smaller aquariums, but with their territorial nature, a small tank can only support a few fish.  African cichlids can only be kept with other African cichlids, as they are very aggressive toward other fish, so they are a perfect choice for a “species tank”.  Some people might worry that keeping a tank full of only one species might be a bit boring, but with African cichlids, that is certainly not the case.  A 55 gallon tank would support about a dozen adult cichlids which would provide a wide spectrum of colors and personalities in the tank.  One important point about the cichlid tank is that if you want live plants, cichlids are not for you.  Cichlids are constantly “landscaping” the tank, digging and rearranging everything in the tank.  A well-stocked cichlid tank is a real crowd pleaser!

– Discus are a beautiful fish that are thought by some to be difficult to keep.  This is not actually the case.  They do have specific requirements that differ from a lot of other common community fish, but if properly provided for, the discus is a hardy fish.  The discus doesn’t have to be the only fish in the tank, but they do best if they are the primary fish.  They strongly prefer to be in groups with other discus and based on their adult size, they require about 10 gallons of aquarium space per fish.  That translates to about 6 discus in a 55 gallon tank, and this is a large enough group to make the fish happy and to create a great discus display tank as well.

– This term describes a community tank with different schools of fish as the primary inhabitants.  With a small aquarium it is only possible to have a few different types of fish, and only 1 or 2 specimens of those, as the small tank just can’t support big numbers of fish.  Many common aquarium fish when in their native environment are found in schools because they prefer groups.  We are able to replicate this with a larger tank.  One Cory cat is nice in an aquarium, but in a group of 4 or 5 they take on a whole new persona.  A school of cardinal tetras are a beautiful sight. With a bunch of hatchet fish or danios cruising on the surface, you create an aquarium with constant activity and loads of personality.  Given the natural tendency of these fish to live in groups, the “schools” aquarium will have a very authentic feel.

These are just a few ideas.  One should definitely experiment depending on personal preferences and experiences, but most of all enjoy the limitless potential of the 55 gallon freshwater aquarium.

Freshwater aquarium fish species are fish that spend most of their lives in rivers and lakes with a salinity (saltiness of a body of water) of less than 0.05%. The environment where they thrive is different from marine conditions in a lot of ways and the most obvious is the difference in levels of salinity. If you want to take care of a freshwater fish, you have to put into consideration that the fish need a range of physiological adaptations in order to keep the ion concentration of their bodies well-balanced. Having enough knowledge before you start this as a hobby will save you tons of confusion in the future.

Some of the most popular freshwater aquarium fish species include cichlids, catfish, rainbowfish, characins and other characiformes. Fresh water fish vary from the hardy to the delicate ones depending on its type. The water in the aquarium needs special care and attention to keep your fish healthy and happy.

Be consistent in maintaining the water environment because abrupt changes sometimes cause stress to the fish. Toxic wastes, pH level and temperature fluctuations can be harmful to freshwater fish. To avoid ammonia stress or poisoning, change the water regularly. This will ensure you of keeping ammonia levels from becoming toxic. Tap water may contain chemicals such as chlorine and chloramines and this can be the cause of death for your fish so it’s very important to treat the water first. Tap water conditioners are readily available in your local pet store, these are great for neutralizing chemicals. With regard to temperature, always keep it stable. Changing the temperature can cause unnecessary stress on your fish. Know the correct pH level that your fish requires. pH test kits are also available in your local pet store and they’re very easy to use. Increase or decrease the pH level as needed.

One important thing to remember when caring for freshwater aquarium fish species is to be very cautious whenever you move them. Moving the fish can cause them to become weak and their stress level can increase. This will also cause their protective slime coating to fade. A good fish protection formula should be used together with chlorine or chloramines remover to help lessen stress and provide your fish with protective slime coat. Taking care of freshwater fish is not easy so if you don’t have the time or effort and of course proper background, you can just look for another hobby that will suit you best.
