For more circulation, I built a closed loop system with 3 returns; one on each end and one in the middle of my tank. I had an extra Mag 7 laying around, but it was barely strong enough to make a ripple in the tank. I then bought a Mag Drive 1200, thinking it would be strong enough, and it isn't; stronger than the mag 7, but not by much. I actually use a Mag Drive 1200 running my dual megaflow with plenty of pressure/current. I'm seeing now that a 3rd return drastically reduces a pump's pushing abilities.
So, how big of a pump do i need to actually create more movement/current? I don't want so much pressure that my fish are plastered against the glass, but i would like as much comfortable turbulence as possible. Any help is appreciated, thanx.
