edit: If you have sugar sand(small particle) in your tank don't go with too much flow. I learned the hard way and have spots in my tank with bare bottom and spots with 3" sand.

Yeah, I am learning that as well. I have a koralia 1050 and a 750 in my tank and everyday I have to move some sand around

I have a 90 gal mixed.....and am running 2 750gph k's, 1 1050 and a 1400......I'm contemplating changing out one of the 750's for anther 1400




So I vote for waaaaaaaaaay up your flow

Wayyy more flow! Try dual Vortech MP40's. One on each end
