Stand top nearly perfect?

[Kevin Burke]

Hello everyone.
I've read every thread I can find here on stand top preparation; thanks for all the info.
After a couple of days of shimming the stand for my 120 extra tall, then shimming the 3/4" plywood top to get it flat, I've arrived at a flat plane with 0.5 mm being the largest defect and that over the 5 foot width.
My tank is a Marineland 60x26x18 with original frame.
Finally, my question: using a 6mm yoga mat, I feel confident the tank will be well supported; do you agree?
TIA

If it's off by half a millimetre over 5ft I think you'll be fine once you've thrown your yoga mat on.

I set up a 180 gallon on a super uneven tile counter top. Massive gaps and it's out of level by a half inch over 18 inches as well as 3/4inch out over the 6 feet. I recorded filling it in case it failed but it has been 3 years so far.

Sounds like a perfectly safe setup to me.
