Good post on how they function! I played with it a bit. I like the way it adjusts. I like w1 so far with a couple second duration. It gives nice movement under water surface and about half inch waves at the top.
For a 220g tank....I wouldn't reccomend it as the only flow. For a 125...maybe... but a 220 would likely need two of these.
