Picked up my first acrylic tank this weekend. Here's my dilema..... I need to hook a huge sump to it. What would be the best way??? I can build overflow boxes into the corners or maybe the center.....Or just put drains on the back wall..... Plans for the 240 gallon tank is Morays. The sump....probobly 200 lbs of sand 200lbs of rock. I imagine I'm going to need a significant amount of flow between the 2. The tank is no prom queen. Definetly function over form so to speek.... So I have no objections to knocking any holes anywhere I need in it. I look at it as a 240 gallon ball of clay at this point in time. Would like to hear from people that have experience with both kinds the advatages and disadvatages of each..... The way I see it overflow boxxes take up space but I guess if a plain old drain clogged it would probobly be ugly..... Any ideas to get this thing up and going would be great.......
