Yeah I've used it ever since I started SW tanks and I've never had a problem with it. Cures super fast. I hate using super glue when I want to attach coral to rock. I hate holding the coral to the rock waiting to see if it's cured.
Aquamend you just cut off a chunk, roll it up for a minute until it turns completely grey, and attach it to the base of the plug, coral, or whatever its attached to and stick it on the rock. It takes me like 2 minutes total to attach a coral.
