I am currently running 5 Vertex discs. I estimate I am putting about 1.7 CFM out per disc. Probably not a perfect distribution of CFM per disc due to valving.

I am going to move the diffusers shallower next winter. At 5 PSI, even with the de-rate for 10,000', my pump will make almost 10 CFM. Only downside to that is when the run off comes, the diffusers will be sitting in shallower water instead of fully mixing the pond and flushing nutrients.

Here is the pic from today. The hole that is open is a dual vertex. It is the shallowest diffuser and the most aggressive plume. We definitely made progress each day over the last two days. Now the question is will it just dome right back over quickly??
