I agree with this. Maybe I'm lucky it has been three years for this tank and who knows how many more with the previous owner. It is better to be safe then cleaning up waterIf i were you I would drain it and put a piece of 1" insulation Styrofoam between the tank and the stand. I have seen a few massive tanks blow out because of something like this. there is odd stresses being put on an uneven tank and over time with sealant becoming weaker it will go bad. that pad is like $20 and will give you peace of mind.
