Or instead of the cinder block (rocket engineer for current stand OR cinder with slightly larger tank)

I've got the tank filled on the stand outside now. How long should I leave it before I say "yep! It's good!" and drain it to bring it inside?

I'm curious about the water level inside the tank.
Is the water level at the top of the tank even from side to side and front to back?

It's a shade off, but it's set up in my garage which is slanted. It IS full to the rim, though (even though my ATO prevents that when it's set up) and even though the stand has close to an inch of wobble before it is weighted down, it's only got a few mm at most when it's full. I'm assuming that's a good thing. Or at least hoping it is.
