Turbelle Stream Advice needed?

[jsweir]

I have a 75 gallon sps dominated tank with a bluline 30x pump return from the sump going through a scwd/spraybar setup. I am supplementing the flow with two ~225 gph powerheads. I hate the heat gain of the powerheads and after scouring the forums, have decided to replace them with a tunze stream. I have about 3" of sand and most of my coral is mid to top of the rock with the rock ending about 4" from the surface. The tank is drilled with 2 - 1 1/2" bulkheads.

My question is would my 75 be better equipped with a single 6000 on a 7091 controller or should I opt for the multicontroller and two 6000? Or should I get the 7091/6100 combo?

Also, what would be the best placement for the recommended setup?

Thanks in advance!

You will probably want to wait for Roger's response, but I can tell you from my experience that the 6100s are way to much flow. I have the 6000 with controller in a 120 gallon and it is just perfect. I would think you would go with something a little less powerful than two 6000's.

The 6000 and 7091 is a good choice but you have a lot of flow from your return so it might be too much. You could step down your return while you are at it and gain a substantial energy savings. The GRI pumps are the best in my book.
