Plywood thickness

Robw · #1 05-23-2009, 06:32 PM

Does anybody have any suggestions on the thickness of plywood for the top of my stand. Its a metal stand for a 4x2x2 tank made from 1.5" square tubing with no cross brace. Also foam thickness suggestions?

Will the tank sit directly over the metal bar that the stand is made from? Also, is the tank rimless or custom built?

^ What he asked...although I would be more interested to know if the tank is "trimless", rather than "rimless", as all tanks have a rim!

Safe to assume you're using the plywood to cover the skeleton of the stand ??

If so, the plywood will offer absolutely no structural strength as the skeleton will bear the weight of the aquarium.

I hope it helps.

The tank is trimless. The sides of the tank are flush with the bottom pane of glass. I know the side covers for the stand will offer no structural support as they will be attached to the steel skeleton with magnets. What I need to know is how thick the plywood between the top of the stand and tank should be. And what thickness of foam between the tank and plywood I should use.

Really, the plywood doesnt support any tank weight in the middle. The glass has enough strength to be supported on the edges only. Thats how tanks with trim are. The trim holds the tank off the stand. But, I would use no thinner than 1/2". The foam, 1" should be fine. I'm using 5/8" ply and 1" pink foam under my 150g.
