I have a single 150 on a 6' tank, (along with some other power heads). I have it horizontal about 2" below the water line.60% Change between constant and pulsing. Rics and the bubble don't like the flow so they are at the "calm end" Everything else is happy happy! Wanted to upgrade to the dual Gyre with controller, but I have done too many upgrades over the last cpl moths.....so it will just stay on "the list" for now!
Maybe move the euphyllia to a more sheltered spot, and run them around 50-60%?
