thanks for the link--very detailed with pics also.
Never have tried that epoxy before--my concern is larger corals always been pushed off by urchins and turbos.

I have used the two part putty that is an epoxy and turns the colour of corraline--but I find that over time it fails

I have 4 urchins in my 60 gal including a very large longspine. I've never had this technique fail me. Sometimes they knock the frag off the plug if it hasn't been given enough time to encrust but the plug itself never budges. :)
