Happy to share, so basically design the “floating” reef so that I can control the flow in different area. I’m using 2x Maxspect Gyre and 1x Jebao wm Both Gyre are placed at the top right side of the tank, facing upwards to prevent direct flow onto the corals. A Jebao Wm is placed under the rock works providing strong flow to prevent detritus from accumulating on the sand bed Jay Regards
