Re: [APD] plywood under tank?

["S. Hieber" <shieber at yahoo_com>]

If it's a standard commercially avaialable aquarium, the bottom glass doesn't touch the surface underneath, only the bottom rim rests on the supporting table or stand. So your only concern is to evenly distribute the weight around the rim. This isn't usually an issue with small aquaria like 30g or smaller. But I have the regular commericial types, like All-glass, perfecfto, develop cracked rims if they are installed off level or with an uneven weight distribution -- it's rare but it happens. You can use some foam strips (sold at hardware stores for insulation on doors and windows)  under the tank to try to insure good contact and distributed weight. Leveling is a matter or filling eh aquarium, check for level with a spirit level and then emptying, adding a piece of playing card or two until the aquarium registers level when full. If the aquarium stand rests on a cement slab floor rather than wood or carpet, then you won't need to fill the aquarium to check for level. But if
 it sits over something with more flex than cement, it might register level when empty but not when full.

good luck,

If it's a glass tank it's unnecessary. All the weight rests on the 
plastic rim anyway. I forget the exact burst strength of tempered glass, 
but you would have to fill your tank to the top with concrete to be in 
danger of the weight breaking the bottom.
