A lake compressor sits on shore in a sheltered, ventilated spot and pushes air through weighted tubing to diffusers on the bottom. The rising bubbles lift deep water to the surface, which mixes the pond and stops stratification. Many units are the compressor alone, so check whether tubing and diffusers are in the box before comparing prices.
