I like using frag rocks like those pictured below when mounting coral in my tanks. It adds a fair amount of stability to each piece of coral. I got a bunch of them years ago and cannot remember where I got them, but I am starting to run low. They look like these:
I found and purchased these Tideline rocks:
But I took them out because they started to sort of fall apart and disintegrate after being in the water for a couple of weeks. Does anyone know where I can find something like the frag mount rocks in the first two pictures? I am not sure what they are made of, but they look and feel like rock, and I have been using them for years in SPS tanks without issue.
