So its 2am, Im just now getting to the point of filling the new tank. Transfer of livestock went well, plumbing not too bad, everything is looking good.... but then I notice as more and more water is put into the new tank, the level from front to back seems to get worse. I think the weight has caused my floor to give a bit. Everythig was level before water? Its only 105g so its not really a ton of weight but there is about a 1/4" diff from back to front. And I made the stand a little taller than normal. Im frakin out that this thing is gonna tip. The plan is to drain the tank down, and get into the crawl space and put up a few 4x4's for extra support. But my real ? is, will powerheads pointed to the top of tank be enough for gas exchange/oxygen to keep everything alive over night without running my overflow/sump/fuge/skimmer?
