The filter tube on a fish aquarium is part of the filter and pump system that sucks the soiled or dirty water up from inside the aquarium and then distributes it through the filter system. The filter tubes typically extends downward at least half or three-quarters of the depth of the aquarium. Longer filter tubes, which rest several inches from the bottom of the tank, are efficient because they help to collect the waste that tends to gather at the bottom. Many pet shops sell filter tube extensions that simply attach to the existing filter tube. Be sure to write down the model of the your filter and pump system in order to get an extension tube in the right diameter.
