Is it best to put live rock right on the glass, or to put it on top of something so that it's not touching it? If on top of something, any suggestions? One idea I had, was to put egg crate on the floor (the kind that was used during the days of plenums... does anyone still use the Jaubert/Berlin Method??), fill in the holes with sand, then put live rock on top, such that it's supported by the egg crate, and finally fill in the sand all around. Any thoughts on this idea?
Going on a tangent, another thing I've been wondering about is live rock touching the vertical glass in the back. Is that a no-no?
