Hey Dang how have you been?
Man I stepped away from this hobby for 3 months and now there is a poll for everything!!! Haha
I will be keeping Sps up closer to the LEDs and then LPS mainly all around the tank, no sorties, no nems, I will have some ricordeas/Yumas in the shaded areas as well...
If I remember your return pump is not to produce flow in your tank really, more so to just move water through your sumo a a good pace.
I really like the MP40s but the cost is semi ridiculous lol the big thing I'm debating on is 2 of those or a reeflo hammerhead and 4-8 closed loop holes in the top of the tank for my main flow. I think the hard part is that the rock work won't be normal, this is an island tank so the overflow and rockscaping will all be in the center of the tank.
