I currently have a 90 gallon SPS dominated reef and I'm using a RKL controller with (2) koralia evolution 1400's and (1) 750. I can't take the clicking anymore and I'm ready to finally go Ecotech. Can I just use (1) Mp40 for the entire tank and get enough movement? Or maybe (2) Mp10's (glass to thick?)Return flow is from a Mag 7. Thanks!
