Hi, I'm considering using two tanks for my new sump. One would be used for a refugium (55gal) and other "stuff" and the second (14gal) for live rock. This for a 90Gal FOWLR tank. These two sumps will be in the basement so I'm not restricted by space. Does anyone see a problem in this design? Also, does it matter if the LR is before or after the fuge? Thanks for your imput
