Yeah, that is why I only put in a little water. I have the wood shims, but maybe cedar shingles would be better. If I use shims what about the center of the stand. It will not be supporting any weight. Maybe put some under the center also just enough to support the tank. No adjusters.
Yep, center also. .5 inch should be easy to fix. Might have to shim the back also. Wait to do it until after you locate your level. Night
