lol, you could do a chernoble themed tank
Speaking of the egg crate, do you know a cheaper place to get egg crate than homedepot?
Ive never heard anything bad about people using styrofoam in their tanks, I beleive styrofoam in inert about 14 days after production. Its just the concrete we cover it with to make the rocks takes a bunch of washing before it wont mess with the PH in the tank. That might be where people have run into problems in the past, but truthfully, styrofoam rocks (with real rocks covering most of them) has been something I had been thinking about for my next tank. and don't think its very dangerous at all if done correctly..
The other thought I had was in regaurds to the black diamond. It is crushed iron and coal slag, which is fine for fish tanks, it might even be beneficial to plants. The onth thing you have to keep in mind is that this stuff is exrenely sharp and abrasive since it is intended to be used a blasting media. These rough pieces can be very damaging to bottom feeding fish like Corydoras. Ive heard reports of cats losing their barbels after being in this stuff for awhile, they can still eat and what not, they just don't have their barbels.
Just my two cents.
