There are several styles and designs available to suite your specific needs as a fish owner, whether you’re wanting something low maintenance, attractive, or just a healthy and clean environment for your fish; a filter for your specific needs is definitely available. I will be able to provide you with information on different external and internal filters. This site will also be able to guide you through your actual purchase of a filter filled with much value for your tank.

Why Fish Tank Filters?

This is the only way you will have a low maintenance and healthy environment for your fish. If you don’t buy a filter or end up purchasing the incorrect one, you will be resentful of having to manually clean your tank frequently. The correct fish tank filter will prevent this.

Internal Fish Tank Filters

These fish tank filters consist of the following: sump tank and the under gravel.

The under gravel filter (UGF) is a plastic grate that is assembled under the gravel or the substrate of your fish tank. A tube rises up out of the grate, which sucks water down through the gravel and then back up the tube. Most of the debris is removed as the gravel acts like a filter through this process; cutting out your need for expensive cartridges.

The Perfecto brand has been around for over 35 years. They build underground fish tank filters with different aquarium sizes in mind. Sizes range from 10″ x 20″ to 72″ x 24″. Prices range from $14.00 to $80.00

External Fish Tank Filters

Just like the name references, all the fish tank filtering is performed on the outside of the tank. Filtered and unfiltered water are both kept separate. Water is pumped in and out of the tank providing your aquarium with consistent clean water. External filters are the best and the most expensive filters on the market.

The EHEIM Classic Canister / External Filter is a very popular external filter. Sizes range from 66 gal to 396 gal. Prices range from $80 to $350. Most people who have used this filter stated that this was the cleanest they have ever saw their tank.
