@ReeferMadness80G Looks like I'm going with a 5.5g sump... this is/was the ATO resivoir for my 75g. Looks like I need another one.
Oh and my Scottish terrier, Argyle. He was begging for attention/dinner. He's a daddy's boy.
When my fiancee gets home I'll get her to help me measure and photograph the back chamber. Have you ever tried to hold a tape, straight edge, and a camera phone at the same time? I need another two hands! Here's a rough picture of the pump chamber, which is where the overflow would have to go... I'm not sure where the return would go with the overflow box installed.
Are we talking like a hang on overflow? Or one to be drilled for?this thin plastic cuts easy with a sharp razor blade. Just please don't cut yourself or drop the razor in the tank, you must prepare for both of those things. Cut on this red line on each side and then you should be able to wiggle that divider enough to break it from the bottom. This creating 2 separate chambers, don't worry about it, you're going to be filling the back up quite a bit anyways. Now you should have more than enough room to add your overflow box.
