I'm sure you'll find out as soon as you get it, but egg-crate is very brittle so you'll want to take that into consideration when you're stacking your rocks on it. It's a a great way to keep your rocks in place, but I have to admit I don't think I've seen anyone use it with a bare-bottom tank. More commonly I see people use starboard sheets (cutting board plastic sheets).
