But, if the leveler is attached to the side and not to the under side of the bottom it should work fine. (I don't remember how the ones I used are attached.)

Plywood is stronger than MDF, and lighter in weight, but to use it you have to cover the raw edges of the plywood, which can be a nuisance. Also, most plywood we can buy without paying a big price is warped before we ever get it. Even if it isn't I always found it nearly impossible to keep it from warping after I cut pieces to size. To coin a phrase - they don't make it like they used to.
Alright then MDF it is . It should be ok for a 24" X 18" surface with 3/4" inch thickness, given my 48" X 18" MDF stand holding my 80 gallon is doing perfectly ok for so long. Thanks again!!
