I have to wonder if that stand was really built for a trimmed tank, 1/8" ply is doing nothing for support of bottom as rimless typically needs.
I would drain the water into brutes, remove tank, make corrections.
It will be a headache to try to make corrections w/ tank on top of stand, and it would be a dangerous headache if tank was full.
3/4" ply is needed, and it should have a couple 1x or 2x braces under ply as well running front to back
I bought the tank and stand from the same local company.. who also did the installation. I would hope they knew what they were doing. If C2C says it needs support, i'll be calling the company who did the install and they can come over and fix the issue.
