I have a 75 gal reef tank with some stonies, LPS, leathers, button polyps, mushrooms, etc. I have a 1200 gph return pump in my sump. After all of the tubing back up to the tank and through a SCWD, I'm getting roughly 800-900 gph. The two returns for the sump pump are in the top back corners of the tank. They are pointed down at the opposite corners in the front of the tank so they essentially make an "X" pattern of water flow in the tank. I also have a small power head, center, on the top of the back of the tank pointed down at the bottom of the front of the tank. This powerhead is about 120 gph so in total I'm getting 900-1000 gph or so.
I'm thinking about getting 1-2 powerheads in place of the small powerhead in the top center of the back of the tank and I'm not sure what to get. I would like the total GPH to be between 1800-2000 GPH (hopefully that's not too much). I'm not sure if I want to get two small koralia (size 1 or 2), one bigger koralia (size 3), or one or two regular powerhead(s). If I get one unit, it would probably be pointed in the same direction as the one I have in there now. If I get two, I would put them side by side in the same spot and point them to the bottom corners in the front of the tank, essentially going from a big 1 "X" pattern to 2 smaller "X" patterns in the tank(one on each half of the tank). Hopefully this makes sense. Which do you think would be better? Any feedback would be appreciated.
Thanks,
Keith
