Need help with aquarium stand.

I built my own stand for a 60 gallon rimless cube. I was testing the tank on the stand and it doesn't look like the plywood is flat. There is a bump on the right left side thats causing the front left edge to float. They screws are covered, so pretty hard to remove them. I added about 15 gallons to see if it would help and so far doesn't look like much change. Do I need more water or wait longer in it to get the plywood to flatten? If it can't flatten out by itself some options I was thinking of are pouring some self leveling epoxy, this foam pad, maybe a sheet of 1/8th ply? Suggestions?

Mine sits on a thin foam pad. Maybe 1/8" think.

It's kinda like neoprene foam. I think some people use thin yoga mats cut to size.

So it is sitting on foam. In the second picture you can the edge of it sticking out from the corner of the tank. But i can still slide a card under it with no resistance. I'm wondering if it'll even out if just leave it alone for 58 hours or get something thicker like a yoga mat.

Looking back at this photo, i can see the bumps shadow. It looks like the plywood bunched up? I'm going to try to remove a screw or two.
