Styrofoam under rimless tank ok?

[islanddave]

I have my 100 gallon rimless on 3/4" plywood and on top of that 1" white Styrofoam.
After I got the tank set up I noticed that one corner of the foam has a chip out of it.
Is this a problem?

Thank You

Why? Did manufacturer reccommend that?

Yes they suggest plywood plus min of 5/8 white styro........question is the chip ok?

IMO all the weight rests on the black trim, not the bottom glass which should not be touching the styro... So I'd rather see the trim corner on solid styro. You could cut the styro sheet in half and move the 'chipped' corner to the back center...

The trim is about 1/8 thick......i believe its there to protect the glass from bumps and such. This is not a trim like a marineland tank or such.
Manufacturer states that the tank need support across the entire bottom of the tank.plywwod plus min 5/8" white styrofoam

i think that as time goes on the foam will start to deteriorate and that looks like a thick piece i have had my tanks on top of plywood for more than 40 years and never needed styrofoam
