Leveling a tank

[Rob S]

I'm working on re-leveling my cabinet before putting the new 8 ft. tank on it. I've got it shimmed up really well but I wanted to get some opinions on material to place on the top of the stand that the tank will eventually sit on. (sandwiched between the tank and stand) I've bought a sheet of green board type insulation that was recommended by a LFS. The other choice I bought is a 1/2 inch sheet of styro-foam (Sp?) poly-shield. (This is what I had the old tank on)

Any thoughts on this? I want to add it for that extra layer of leveling and so the acrylic isn't sitting right on the wood.

I would think the styrofoam would work pretty well if it's the type that you can pick up in the 4' x 8' sheets.

I'm not familiar with the green board type.  When I read that, I thought of green (moisture resistant) drywall

[Rob S]

Yes, it's the 4 x 8 sheet type. I've used it before but then I heard the other type provided a more solid base but enough give to add support. It's not the drywall type, it's more of a pressed insulation. Thanks Marty!

Anti-fatigue floor mating from Harbor Freight works pretty good IME

If you want additional support but want the weight evenly distributed, is there enough space (height wise) to put a sheet of plywood down and then foam on top of that?  Or will that have the tank sitting too high above the trim?
