Power Flow Undergravel Filters

How do you remove settled wastes from the gravel in your aquarium? Use these powerful undergravel filters to keep your aquarium water sparkling clean.

The filters are designed for high-volume water flow and have special built-in mechanisms to prevent gravel or fish from entering the system.
The removable carbon cartridges and air diffusers (two of each are supplied) help purify the water and provide a steady stream of fine bubbles.
Please note: An air pump is required but not included.
