hello people, need advice please, i'm a novice and a chick, could use some help please. I had a stand made for me for my 72Lx18Wx20H (100 gallon) tank, i finished it off with some levelling compound, sanded it and then painted it (i have pics of my progress if anyone is interested, i will post). I then put it in place in my lounge room. Before i filled the tank, i had double checked with a spirit level that it was level, but now after I had filled the tank, I have noticed that it differs from one end to the other of 5mm, is this ok? or will it cause my tank to bow and break. Its sitting on a foam base, and now I'm scared that it's too uneven. Will this be ok? I want everything to be perfect first time round. thanks in advance.
