Fishtank slightly tilted

Just be careful that you feel you are confident about why it is sloping?

I have a house with floorboards and walls that run off level all over (think the builders must have been somewhat "relaxed" when building mine!!!). However, might be wise to simply look around and see if there is excessive weights on your floorboards in that area, e.g. a huge solidwood sideboard or something...you could be putting excessive stresses on your joists. If not, then its probably just the natural movement of the wood and dont worry about it....

Its really surprising how much water weighs and if soemone was putting a 150 Gallon (absolute whopper!) in then I'd probably looking a doubling up the joists first!!!

But with tanks under 100G it should be absolutely fine!

(sorry, was that you asking for the time and me teliing you how to make a watch????????????)
 
I had the same problem at my place. Didn't bother to check the table because it was in the middle of the house, not near the foundation which has settled. After putting the water in, I noticed that it wasn't level. Luckily I have a full wood shop and garage available to me so I smily jacked up the high end of the table and trimmed down the legs a touch, then lowered it, checked with a level, the jacked again and sanded until it was level. Of course I could have shimmed the low legs but the table is there for the long run, and isn't worth anything for resale, so adjusting the table looks better in my opinion.
