Gorilla glue for live rock

Just guessing here, but I think it may be similar to epoxy in that after it cures, it is inert. I've used it to seal the screws when I mount bindings on to my skis due to the water proof nature after curing. It is quite reactive with water prior to curing and if I remember correctly, use of some water on surfaces to be bonded is recommended to aid curing. So perhaps as long as you bond components outside of the system and allow sufficient curing time, it might be ok. But again, I'm just speculating. Looks like hhunkybod has had no problems.
