I am draining my 75g to drill in a corner overflow I will make of tinted 1/4" acrylic. I moved my 3 fish and corals into a 30g in the bedroom and my 160 lbs or lr are in a tub in the kitchen. I acquired a free 55g so I had glass cut for baffles in a sump/fuge. Anyway, after it's drilled and I build my new stand for the 55 underneath and new easier to access hood for my vho's, I will set it back up. I will have a mag5 and mag2 flowing through two 3/4" hoses 4.5 ft back into u-tube returns. I am ordering a sureflow 1600 kit for my maxi900 and I want to add a koralia #2. That should be enough flow I imagine but I wanted some opinions. Also I have about 60lbs of sand and I want to wash it out, strain out big particles and add about 40 more lbs. But would it be better to replace all sand? I know I will keep enough to put about 3-4" in my fuge but wasn't sure otherwise.
