The styrofoam will compress and eventually be touching the glass. Not a good idea IMO....Better to replace the piece of wood on top of the stand with one that is flat, or a piece of slate....etc..
hmm
i read a bit on this on the web after your post
Doesnt seem like a good idea after all..
HOWEVER, my stand is not flat in the middle and something MUST be done..
Replacing the top is not an option
How about this:
Redo the styrofoam base but differently
Stand-->Styrofoam-->wooden plate-->Tank
If i get this right, the styrofoam would compress to level out stand imperfections. The Wood would prevent anything from touching the bottom of the tank, hence reducing risks.
How does that sound? Please let me know about any flaws in the design
The good thing is that using this method i can cover the wood and styrofoam as above with the black cloth. Replacing the panel on the stand would mean: New profiles, more wood, more sanding, more filling, more painting etc etc..Now i love DIY but id rather work it out in another way if i can
