We prefer recycled Industrial colored glass for it's purity, vibrant colors and brilliance under water.
Single piece sized especially for the Classic EcoAquarium®.

I ordered an extra rock to go with the new EcoAquarium. The rock was very nice, but a little smaller than I'd hoped. In fact, the rock that came with the kit was also small. I ended up using both of the new small rocks with the big one I already had. Otherwise I'm very happy with it - and now I have 3 colors. Not that the frogs notice.
