Id install it at 15ft deep. I'd say 1 acre is that deep and moves up to shelves for spawning from there.

I don't have ANYTHING installed yet. I have 2 ponds and was wondering if I could use the 2-diffuser head in the other pond.

Is there a product that diverts the air from 1 pump to alternate between LP valves/air lines?

I want to use the same pump for 2 ponds just have it kick on at different times.

God has blessed us with this day, what we do with it is up to us.
