Tank transfer has also been decided to be monday, labor day. I'm going to take down the 75 starting the thursday before (being a senior means I get out of school early ). I have to move the sump and the stand its going under, move fish into holding tanks, clean out the area, put up the framing and PVC sheets, set up the stand, move the new tank in, and scape and fill it back up. The plumbing I will do the next week, to give myself some time to rest. If your tank can't survive without it's sump for less than a day or two, you have a problem. (Heating and calc/alk notwithstanding)
