Otter, here's some numbers for you to crunch. I sell Vertex systems, and I'm using their figures because that's what I have.
Here's the numbers:
I'll use a max depth of the pond at 10' because that equates to 10' of head pressure like you used in your example.
Using a 1/4 hp air compressor, with the diffusers set at 10' depth, a 2 disk diffuser station will move 3,200 GPM.
So what is the daily or monthly energy consumption on something like this using say $.12/kwh
