Well guys I just installed my mp20 for my55g reef tank and I gotta say it's crazy. My corals were looking different when fully open I can feel and c how the flow targets my tank. Before I had 2 620 seio and compare to vortech they suck. But my ? Is what's does every one think is the best mode for corals . I have it in lagoon. I want to say thanks to my homie vir for coming over and helping me install and for the past year telling me to get one especially tellin me not to go with the mp10! Also thanks HOF for the great pump.
