ware can i get replacement fillters
Answer by • Jan 18, 2021
At this time, we do not carry the filters however, the Penn-Plax Filt-a-Carb Carbon Undergravel Filter Cartridges are available directly through the manufacturer.
Can i use this filter in conjunction with canister filter and water circulation pump?
Answer by • Jul 10, 2019
This undergravel filter may be used along with a canister filter. Before using, ensure the intake tube is not near anything that is causing air bubbles. The canister filter will pull in the bubbles along with water and air will build up inside the canister.
What exactly comes in this package?
Answer by • Dec 14, 2021
The Under Gravel filter will have the plates, lift tubes, carbon cartridges, and air stones. It does not come with an air pump and air tubing.
Do the tubes need to be completely submerged under water for this filter to work ?
Answer by • Oct 02, 2019
The entire filter, including the cartridges and tubes should be fully submerged under water, in order to operate properly. Nothing should be sticking out above the surface of the aquarium.
