Adding a power head to an under gravel system increases water flow through a gravel substrate and improves its filtering efficiency. It also oxygenates water and, in the process, provides needed oxygen to colonies of beneficial bacteria in the gravel which optimizes their biological filtration capabilities. Easily fitted to most under gravel systems, these powerheads come equipped with a tapered riser stem adapter which accepts .5" to 1.125" tubing. Rim clamp firmly holds it in place atop the riser stem and an optional suction cup bracket which allows the unit to hang from an aquarium wall instead of the rim.
Recommended for 10-30 gallon aquariums. Pumps up to 174gph.
