I'm not an expert on structural issues in regards to aquariums, but if it were me I would not attempt to do any of this with a full tank. If I was bent on leveling a tank, I'd be sure to drain it completely, remove the fish and the bulk of the decor, and do it empty using a level. It seems too risky to me to manipulate/level a tank when it's stocked.lestatak said:A buddy of mine, who built the stand for me for free, quite a guy, suggested using a floor jack to pop up the left side of tank with the elevated water level. Once we get the tank level, we use longer 2x4's to stabalize the tank levelng it. This sounds to me like a brilliant solution but it does seem to have a risk. What do you think?
