Water Filters For Fish Tanks

canister filterSeemingly there is no end to the number of manufactures and designs for water filters for fish tanks. Some of these have been around for years while others are here today and gone tomorrow. It’s hard to know which ones you should purchase and what prices you should pay. This article won’t necessarily help you with low prices while your shopping for the right aquarium filter but hopefully it will steer you towards the correct filtration for the particular type of aquarium you have. Whether you have a salt water tank or a fresh water aquarium, choosing a filter that is rated to your tanks environment will ensure that you have a nice looking, low maintenance, clean and healthy system for your fish.

Both internal and external filters are capable of keeping the nitrogen cycle healthy in a fish tank. They are also both capable of mechanical and chemical filtration. Mechanical filtration refers to the physical removal of material such as algae or excess food. Chemical filtration attempts to remove dissolved wastes by using carbon; or protein skimming in saltwater aquariums.

Internal filters are typically limited to undergravel filters, corner filters, or box filters. They employ air bubbles or power heads to create the filter action. The materials for mechanical filtering are normally floss or sponges. Chemical filtration is limited to small quantities of carbon or even charcoal in freshwater tanks.

External filters choices include canister filters, wet dry filters, protein skimmers, ammonia towers and much more. They are much more likely to have a larger choice of media than an internal filter. In a canister filter,water is removed from the aquarium and forced through filter media by an external pump then returned back to the aquarium. Wet dry filters, usually used in saltwater and reef systems, draw water off the top of the aquarium via gravity flow. The water trickles through a mechanical filtering media or sock, then flows into a biological chamber. The biological chamber may cpr wetdryincorporate bio balls, bio discs, bio bale or any number of synthetic products. Then the water flows to a protein skimmer and / or protein skimmer to complete the chemical filtration. The water is then pumped back to the aquarium.

Now that you know the basics of the type of filtration systems that are available, it’s time to decide which one is best for your tank. Normally, freshwater aquariums will utilize internal, over the back, or canister filters. It’s worth noting that even though canister filters provide superior filtering over internal filters, they are not always necessary. Smaller tanks do very well with internal or over the back filters. Freshwater tanks over 50 or 60 gallons do better with a canister filter. Saltwater aquariums normally use canister or wet dry filters. You can never over filtrate. It’s better to go one size larger filter than your tank requires. This ensures that the filter is not over taxed by the normal day to day needs of the aquarium environment. It also gives the hobbyist a little wiggle room if there are too many fish in the tank or overfeeding occurs.  Hopefully this article has been helpful in explaining the different types of water filters for fish tanks.
