Gravel Filter Kit

$19.95

Undergravel filters use the aquarium gravel itself as a filter medium, drawing water down through the gravel bed and collecting wastes and debris in an open space underneath. Powered by an air pump, they’re a great way to add extra biofiltration and aeration to your Garden or any aquarium.

DO I NEED A GRAVEL FILTER?

We recommend supplemental aeration or mechanical filtration for tanks with more than 3-4 small fish. If you don’t use an undergravel filter, it’s a good idea to periodically agitate the aquarium gravel or use a “gravel vacuum” siphon to remove trapped wastes.

  • 20" x 10" undergravel tray
