So i am thinking of getting a vortech for my 55 gallon. Right now i have a koralia 750 gph a koralia 450gph and a maxijet pro i think it does 750gph. My plan is to replcae the maxijet and small koralia with a vortech and leave the bigger koralia in there. would an mp10 be good enough and maybe add Another one down the road or should i get the mp40? right now i only have zoas and lps no sps yet.
