So I’m picking up a 110g acrylic tank and stand tomorrow. The tank is used and getting a steal on it. The tank is bottom drilled there are 4 holes equally spaced the length of the tank but dead center right through the middle. So I’ve never had a tank that was drilled that way before so how would I go about plumbing it for a sump and such and keep sand outed the lines or sump?? I’m not above Potentially plumbing it the the back wall and installing a overflow box. From seeing the equipment it looks as tho previous owner had a closed loop system going. Please give me any and all suggestions. Here is a picture so you know what I’m talking about.








thanks again guys for joining in here
