Can-Air Mega Aeration System Manual

Can-Air Mega Diffuser Installation

If there is no aeration currently in your fish pond, the diffuser should be lowered roughly half the depth, and then slowly lowered to the bottom over the next few weeks at a rate of 2 feet every other week until it is at the pond bottom

If the diffuser is lowered to the bottom right away you risk stirring up toxic gases that could kill your fish. Lowering it slowly over time will eliminate this risk.

Can-Air systems with one, two, three, or four diffusers can be housed in one post-mounted cabinet.  Two of these systems can be mounted in back-to-back cabinets (preferred).
