Water uneven in tank..

[Mudfrog]

So I just set up my 120 gallon and the water is uneven by about 1/4-3/8". It's bad enough to where my dual overflows will not correctly work together the low side works fine but the high side gets way way too much water in. I'm assuming I will have to move the tank to another spot as I assume the floor in my basement has a little bit of a slant, Is there any alternatives as I really really want it set up right here..

you can shim the lower end up, but you would need to drain the tank a bit so you can lift that end...

Drain the tank and fill it with even water. This is very similar to unlevel water, so I guess the solution should be the same.

Shim underneath the tank or the stand? It would be quite a bit of shimms I believe. I just measured it, it's 3/8" difference.. I put a level on the top of the tank and it is off but not a ton, the bubble just barely goes outside of the line but I guess with water you don't need much.

you will want to shim the stand so the tank is still supported evenly... and if you go to HD you should be able to get those wood shims and you should only need a few of them... you can get a big bundle for like $10.

No one's gonna say to raise up the lower overflow? Seems like less work to me.

depending on how the overflows are setup it might be easier...

Dual Corner Overflows with Durso Standpipes, so if I follow what your saying it won't work.

I'd shim the stand instead of the tank.
