Looking for feedback on getting my stand top flat!

I figured this deserved a new thread since the topic has changed. I am trying to get my tank stand top as flat as possible and have come up with three options. I would love to hear some feedback on what others would do. Keep in mind that my tank is a rimmed 90 gallon glass tank and the stand is way overbuilt with 2x4s and a 3/4" plywood top. The top has imperfections like most pieces of plywood do. The stand and aquarium is level to the floor, there are some areas where the trim does not meet the plywood and I can slide paper underneath.

Option 1

Stand-->3/4" plywood-->spongy foam 1/2"(compresses a lot)--> 1/4" plywood (flat)--> aquarium

Option 2

Stand-->3/4" plywood-->thin foam 1/4"(compresses a lot)--> 1/4" plywood (flat)--> aquarium

Option 3

Stand-->3/4" plywood-->polystyrene rigid foam 1/2"(very little compression--> 1/4" plywood (flat)--> aquarium

Glass or acrylic tank? If glass don't worry about paper thin gaps. If you are worried use the polystyrene with the tank right on that no 1/4" plywood.

Dilution is the solution for the pollution.

It is a glass tank with the rim. Why would you say no 1/4" plywood on top of the polystyrene?

Because it's not needed and will hurt more than help. You want the poly for its crushability. (think memory foam mattress) Putting the ply on top of it will take some of the best quality of the foam away.

Also, if you're barely sliding paper underneath, I wouldn't worry about it. You'd be surprised how much of a gap 720 lbs of water will even out for you.

Haha but everyone has said that foam should not go under a rimmed tank. The issue is I can slide a paper under 1 whole corner

this does worry me....for some reason I am being overly cautious here, maybe too cautious. I could rip off the existing 3/4" plywood and head over to the lumber yard and look for some other type of "top".

My other option is to rip the 3/4" off and just level it off with the existing frame of 2x4's and make it an open top

You sure it's the plywood? I've seen rims that were off a few thousands. Never been a problem.

Rubber mat or cork would work fine.

so I couldn't take it anymore! I ripped the top piece of plywood off to discover that the "frame" was completely level, so the plywood was causing the issues. I have thought about leaving it as an open top since there are no issues right now. Here is a pic of it just to make sure that having the rimmed tank on here would not be an issue

If it were me I would either set the tank right on it with no plywood or just a piece of foam insulation again with no plywood .
Plywood has flaws and if the frame is level . There is no need for the plywood

Just my $.02

This was my thought as well....why add something when there isnt a real need for it. On another note, I did contact my manufacturer of the tank, Miracles, and they recommended no foam under the tank
