Tank level help

[corey.nolta]

In the process of a 250dd build. Rock work is done, first 60 gallons of salt water are in. As I was filling I noticed the water line wasn't quite as level as I was hoping it would be (Yes, I checked numerous times throughout building the stand and placing the tank). I think it's more my floor, as I live in a old house, and being such a large / heavy tank. I do have metal floor supports under the tank - three to be exact.

I measured and the water is 1/8" higher in the front left corner (both in front to back and right to left). How much stress will that cause on the tank? Is it something I need to try and shim or is it minimal enough to not cause issues?
My stand is made of 2x6's and 1/2" plywood top. If I need to shim it can I just lift the corner to shim without worry of flexing the tank and cracking??

Let's hear some advice!! Halp

Good work on making sure its level while water is going in. A vast majority of tank cracks are due to not being level.

Yes you are totally fine to lift the stand to shim it. Make sure you shim the stand and not the tank. Use a lot of shims so you have lots of contact between the stand to shims to the floor. You don't want a pressure point on a stack of skims to compact overtime and lose your level.

Good luck picking it up even with just 60 gallons in it.

Got it leveled! Well as close to perfect as it's going to get. It was actually super easy to pick up. Three to lift, one to place shims. Took all of ten minutes.

60x8=480 lbs of just water. You have some strong friends ! Congratulations, great job recognizing and fixing the problem.

It's not like we lifted the entire thing a foot off the ground. I was only off 1/8" off. Three people lifting from one side just enough to shim such a small amount....it wasn't near as bad as I was thinking it would be.

Plus I carve ice as part of my job. Each block weighs 300 pounds, so I'm used to maneuvering heavy objects.
