A fish tank filter can be one of the most important parts of your fish tank, especially when it comes to keeping the tank clean and the fish healthy. Often you wont even notice how well the fish tank filter is working unless it stops working. Once the fish tank filter stops working, the waste can build up quickly and things can start going downhill fast.

Types Of Fish Tank Filters

Probably the most common type of fish tank filter you see at discount stores is the box filter. These both hang on the inside or the outside of the tank, and usually have a charcoal filter cartridge in the main box. The water from the tank is circulated up into the box, through the filter and then back down into the tank. They are rather slow but steady and can usually be found fairly cheaply. Theyre not the best fish tank filter you can buy, but they can do the job, are easily found and are readily available.

Another type of fish tank filter is a filter that covers the bottom of the fish tank floor and is then covered with rocks. In theory the debris and other garbage are filtered out after they hit the bottom of the fish tank. These are really neat looking and work fairly well, but not as well as the box tank filters.

There are plenty of instructions on how to build your own filters as well, and these can be the best fish tank filters you can find. Wet/dry tank filters sit on the edge or rim of the fish tank. The tank water is slowly trickled over filter media, which can be one of several kinds. As the air and water mix along with the filter media, the water is filtered and several chemical processes occur. This is probably one of the better fish tank filter ideas, and it is fairly easy to do yourself at home. Directions can easily be found online, and often buying the materials for the filter is cheaper than buying a ready made wet/dry fish tank filter.

A fish tank filter is a vital component of your fish tank. It not only cleans the water, but also allows more oxygen to be mixed in with the water. Fresher, cleaner water helps keep your fish healthy and will help them live longer lives. A tank filter doesnt have to be a really expensive item, one that competently does the job can be used and doesnt have to be top of the line.
