ok i have a wall dividing my dining room and hallway i was thinking of double backing two tanks on either side of the wall one fish only the other reef. these 400l tanks would be connected with a 200l sump under one of the tanks and the two will share water andpumps etc. so could the LR in the reef supply the fish only too? and the tank with the sump not under it will have two pipes through the wall to the sump. with two separate return pumps. I want to know will this work and will it work well?
