i have a 46reef and a 120 fowlr.am going to be moving soon(not really looking forward to it).i will have a full basement in the new house,so im going to upgrade my fowlr tank.im still undecided on the size but it will be in the 500 range (96x36x30) with a 300 gallon sump.now my question is,should i tie my 46 reef into this system once it is up or should i keep it contained into one.it seems to me that the larger volume would help with stability,only concern i have is the water from the fish only tank.should i be worried about that ?
