Levelling the aquarium

[Ondion]

Hello everyone ,

I am keeping my new 90l aquarium under two cabinets, however it is extremely uneven I think it's because of the floor.
Would you say that it's better to keep the tank on one cabinet and focus on levelling it as it may be too difficult to level both of the cabinets together as they are separate?

It is probably a stupid problem but I really have no experience in these sort of issues, I will appreciate any advice.(Area around the tank is wet as I was investigating the issue there are no issues with glass ).

One cabinet, or two with a thick plywood underneath the tank to support the bottom and avoid the gap/stress point that could create pressure issues that could force the bottom to break.

I have a piece of plywood and some foam cut to the same size of the tank under mine.
