Freshwater Aquarium Filters - What To Choose
Posted on 01. Sep, 2010 by admin.
Why do you need an aquarium filter?
It is possible for freshwater ponds and lakes to naturally achieve an ecological equilibrium without external help. By that I mean that they are able to reach equilibrium whereby the fish population adjusts according to conditions and fish excreta is all dealt with biologically and there is no build up of ammonia, nitrites and nitrates making the water poisonous to fish.
Aquariums are too small to achieve a balance without help. The fish would very quickly die from toxic water without external help. The main reason is because we all like to fill our tanks with a density of fish which far exceeds that found in the natural world. Fish in such high numbers produce far more waste than the resident bacteria can possibly cope with so even changing one third of the tank water every week is not sufficient to keep the water clean. In addition it is imperative that you have a freshwater aquarium filter of some kinf.
How do Freshwater Aquarium Filters work?
Any filter system worth its salt should be capable of performing in all three ways; mechanically, biologically and chemically. For special purposes like getting rid of parasites or green water a fourth method called germicidal or algaecidal exists which uses a UV steriliser.
Mechanical filtration involves using foam and/or fibre to remove large particles like uneaten food and fish waste. The filter medium varies in texture from coarse to fine, large particles are removed first by the coarse filter and then small particles are removed by the fine filter.
Biological filtration uses colonies of two types of good bacteria. Fish excreta turns into ammonia which is very poisonous to the fish. One kind of bacteria converts the ammonia to nitrite and the other kind of bacteria converts the nitrite into the much less dangerous nitrate. The nitrate concentration is kept down by means of regular water changes.
Activated charcoal or ion exchange resins are used in chemical filters. Chemical filtration is normally only needed in the first few weeks of a new tank being setup.
The Five Main Types of Aquarium Filters
1.In-Tank filters also called corner or box filters are among the first filter designs. Most of the modern filters used today are based upon these filters. Normally powered by an air pump they work by pulling water through a variety of filter media. Compared with other filters available they are not very effective but they are reasonable in price. The most common uses today are for breeding and hospital tanks.
2. Undergravel filters (UGFs) comprise a grid of plastic pipes with small holes every centimetre or so. The grid is situated under the substrate or gravel thus creating a water space there. Water is slowly pulled through the gravel into the filter pipes by up to four ‘air lifts’. The theory is that bacteria will break it down there. The advantages of UGFs are that they are very cheap and easy to setup and run, and the aeration helps keep dissolved oxygen high. One disadvantage is that they normally do not do chemical filtration. As well as this the small holes in the filter get blocked and waste tends to accumulate because it is not all broken down. As a consequence you must regularly use a siphonic hoover on the gravel and at least twice a year completely clean the filter. To get at the filter you have to remove all of the substrate. It is for this reason that undergravel filters are not as popular as they used to be.
3. Canister filters are a much better choice. A siphon tube conected to a canister and pump pulls water outof the tank and through the canister and a return tube puts the water back in. Usually the canister contains coarse ceramic ‘donuts’ or a coarse fibre, perhaps some chemical filtration medium like charcoal, porous glass or stone for biological filtration finished with a very fine filter fibre. Biological, mechanical and chemical filtering are all perfomed by a cannister filter. Cannister filters are great at keeping your tank water crystal clear. The disadvantages of these filters is that they are not cheap, they use costly media and they require to be maintained every month. They can become nutrient traps if they are not well maintained. This means that all of the fouled filter media actually begins adding nitrogenous waste back into the water instead of removing it. This results in algae bloom and poor water quality! Also you should add an airstone and pump to oxygenate the water since cannister filters are completely enclosed. Overall though, when properly maintained, a good canister filter is hard to beat.
4. Power filters are suspended outside the tank and water is pulled up into the filter by means of a pump. The water falls back into the aquarium after having passed through mechanical, biological and possibly chemical filter media. These filters have the advantage that they are efficient, cheaper than cannister filters and very easy to maintain. Water oxygenation is improved as they are exposed to the air. Power filters are very efficient biologically because they are open to the air so the water passing through is oxygen rich and supports large numbers of nitrifying bacteria. Particularly good is the biowheel version.
5. Wet/dry or trickle filters. They are only included for completeness. Their use is normally limited to very large tanks. They are costly and have been known to empty aquariums of their water if they go wrong!
Conclusion
In addition to changing one third of the tank water every week, you also need an efficient freshwater aquarium filter system to prevent a build up of toxins in the water which will eventually kill the fish. The several choices have been described above. You can now make an informed choice.

If you’re unable to provide a bigger quantity of water, Betta will not actually complain! The only requirement they have is availability of adequate hiding locations within the tank. If you are placing them in tanks of smaller capability, they are going to be under stress and their lifespan shall be shortened.
Bigger tank is good for the Betta as a result of the temperature there is not fluctuating frequently. In the larger tanks, the quality of water will also be stable.
There usually are not many necessities of treating the water for Betta. You’ll be able to even use faucet water for them. The one precaution it is best to take while utilizing the faucet water is to keep that water apart for not less than 24 hours so that the chlorine dissolved in it would go away. Never use distilled water for them as a result of that water will take away most of the minerals.
If you are a beginner, the water you will have used for the first time in the tank should be kept there for not less than a couple of weeks so that the filtration cycle will get set.
Bettas are used to sluggish transferring water. When you introduce the filtration system which creates a movement of water contained in the aquarium, they may get uncomfortable. They are not looking for much turbulence in the water as a result of they will not be able to come back to the surface for breathing. They’ve a peculiar system beneath which had they can take air straight by coming to the surface.
If your aquarium is furnished with a heater, you should always have a thermometer is obtainable handy. This is for monitoring the temperature of the water because sudden fluctuations within the temperature will be really demanding for the Bettas. Usually they are comfortable with the temperature range of 75-85° F.
The gravel in the aquarium ought to be fastidiously laid. It ought to resemble to the pure surroundings in which Bettas are used to live. You cannot take the gravel from your yard to economize!

Fish can certainly perk up your apartment as they lazily float around inside their aquarium without a trouble in the world. Most people may even come to feel strain disappear while you look at them do their own thing. Exactly what do you consider whenever you consider aquarium products? For the best results you really should every thing set up at the least one day before bringing any pet fish back home. Fish are extremely particular about their surroundings, all this will give your tank the time to stabilize as well as get to a good environment for ones fish.
In picking any aquarium you need to take into account what kind of pet fish you’ll have inside it. Go for a manageable sizing so that you can change the water often, and even sometimes entirely clean it. You also want a tank that’s big enough for the fish. Fish need enough space to swim around, and some need a lot more than some others, so you should get one that enables an abundance of breathing room. A rudimentary fish bowl will be OK for goldfish or possibly a beta, for the reason that it doesn’t use up a great deal of space or need a water pump.
Pea gravel is not always required, however, many fish are bottom feeders and so consume foodstuff from the sand at the bottom of their particular natural habitat, so they would require pea gravel. This sand likewise keeps the bottom part from looking much too yucky helping conceal some of the fish food items as well as fish “waste products” between cleanings. The people from which you buy your pet materials will be able to show you everything that you should have.
Pet fish will be needing a specific temperature range to survive, and it is critical that you maintain it inside of that range on their behalf. It makes sense to invest in a thermometer so you’re able to continue to keep conditions ideal for them. You can get designs which adhere to the side glass of the aquarium, or simply hang or drift within the water. Amongst the best methods to manipulate temperature is to invest in a heating unit. When you’ve got a tank for your fish rather than a fish bowl, you will need a water filtration system. Always keeping the actual fish water crystal clear will prolong your fish’s life. In smaller sized systems the water pump and filter will come together. The water pump moves the aquarium water though the filtration supplying oxygen bubbles which will keep the water aerated and then prevents water stagnation.
You could get aquarium water at the shop or merely utilize tap water. Should you use plain tap water you will need to either invest in a chemical which removes the chlorine, or permit a few gallons of water sit out for a few days. This enables the chlorine to evaporate. Whenever you are working with pet fish then avoid tap water and use the chemicals. Make sure you make sure that your water is completely ready before you bring your fish back home and acclimatize the fish prior to allowing them free into their new fish tank.
Different fish need to have different types of nutrients. Serving your fish the incorrect diet may very well be lethal. Learn up on what precisely your specific fish prefer to have and then read the containers so you know you’re getting the appropriate type.
At some point in time you will need some form of fish net. Every now and then you’ll have to take out your fish to clean your fish tank, as well as sadly occasionally you will have to take out a fish that has died.
