ok I have a aga single return 90 gal tank I want to increase me water flow, going to get a mp40-w will it alone be ebough flow in this tank i currently have a maxi jet 12 maxi 9 and a maxi 12 with mod. I also have a mag 12 that I was going to make a over the back closed loop but if I can just use the mp40 I would rather do that. I want to be able to keep a little of everything sps lps softies all of it. maybe just the mp40 then add a mp20 later will they synch together? what does every one think
