When I use just one for the 10g, the flow is not enough. I just tried lowering the pump on the left side which surprisingly decreased the intensity on my higher flow demand corals.
I still don’t know what to do with the display. I can’t master slave it on else mode because it’s way too intense, nearly knocked the polyps off my monti. It’s like it goes full speed now which is 2,250gph. I’m not sure changing the speed helps when they are set to else mode (random flow).
Right now, I have the back pump on the second lowest speed making waves and the front on else mode. It looks alright but not getting those hurling wave motions that have the nice smooth flow and wave motion.
