The Canadian-made Can-Air SS Fine-Bubble Bottom Diffuser is the perfect solution for effective lake and pond aeration. Designed with ease of use in mind, this diffuser lands upright when tossed into the water, ensuring a hassle-free installation. It is ideal for ponds and lakes up to 2.3 acres in size, making it versatile for various water bodies.

Built to last, the diffuser features a durable powder-coated stainless steel base that requires no additional gravel to sink. Simply lower it into the water, and it’s ready to go. With low maintenance requirements and easy assembly, this diffuser is user-friendly and efficient. By moving water slowly over the bottom substrate, the Can-Air Aeration systems significantly improve water quality and can reduce phosphates by up to 95% in many cases.

Can-Air SS Aeration System Manual

Can-Air SS 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).

    Can-Air SS Diffuser

    Posted by Randy Hennig on 15th Apr 2021

    Can-Air SS Diffuser is well built and provides excellent aeration. Easy to assemble and connect. It is much better than the previous diffuser I was using. I recommend this product.
