Can this be used with sand instead of gravel?
Answer by • Sep 30, 2022
This filter is designed to be used with gravel.
Does this come with a pump?
Answer by • Dec 19, 2022
This product does not come with a pump, it includes 2 carbon cartridges, Discard-a-Stone, a fish-saver elbow, and a telescoping ring to adjust the height of the uplift tube.
What is the height of the tubes and are they adjustable?
Answer by • Dec 14, 2022
The tubes for this are not adjustable. The 5.5 gallon measures 5 x 1 inches, the 10 gallon measures 7 x 1 inches, the 20 gallon measures 9 x 1 inches, the 29 gallon measures 10 x 1 inches, the 30 gallon measures 11 x 1 inches, the 55 gallon measures 13.625 x 1 inches. We recommend the Lee's Aquarium & Pets Thinwall Ridge Tubing (sold separately) for a longer tube if adjusting is needed.
If using the under gravel filter, do you also need to use a normal water filter/pump setup?
Answer by • Jun 18, 2025
When using this under-gravel filter, it requires an air pump.
