Kasco Bottom Aeration Diffuser
Kasco Robust-Aire bottom air diffusers provide increased water circulation and the addition of oxygen to the bottom of a lake. These units are typically used in lakes with depths exceeding 8 feet. In the heat of summer, lakes with greater depths are at a higher risk of stratification. By placing bottom air diffusers, you create an updraft of water that helps to circulate the entire lake and reduce stratification. This ultimately reduces the risk of lake turnovers that could cause fish kills.

Installed in a 12-foot lake during summer. Water movement improved noticeably. Fish activity increased and no signs of oxygen depletion were observed. Works well with the existing pond setup.
Abigail Kerr –
Good for deeper lakes. The unit runs quietly and keeps the bottom water moving. Saw fewer algae blooms after installation. Would recommend for lakes over 8 feet.
Peter Jones –
After installing this diffuser, the lake no longer stratified in summer. Oxygen levels at the bottom are much better. Fish are more active and healthy.
