I'm starting to think about powerhead and/or gyres for my redesigned tank and looking for some opinions. My tank is 7 feet long, 3 feet deep, and 5 feet tall. Due to the nature of its design it will be difficult to move powerheads/gyres once it is full. When ran as a freshwater tank I used a single gyre up high in the tank and a closed loop pump within the tank moving water from the top of the water column down to pvc hidden below the sand to help mix and move water up and into the overflows. It did not require much in the way of flow.
I am now considering two gyres up top and either two gyres further down or more powerheads instead to give me more options for adjusting the flow as I transition to a reef tank. The current plan would be for a mixed reef tank with SPS up higher on the rockscape and lower flow/lower PAR-demanding corals nearer the bottom.
Which option would be better up high? The blue squares would be two gyres on either end opposing each other or the pink with two gyres at the back pushing flow towards the front?
What would be a better option down lower? An additional two gyres at either end placed vertically? Or multiple powerheads low at the ends of the tanks?
Looking forward to some opinions here. Thanks!
