I found something at home depot that was $4 a shot. it was a small bottle of gel that was designed for fish tanks. it starts to harden as soon as it hits water. I take my SPS out of the water for about 5 sec while I goop on a bit and put it back in the water and hold it on the spot to be glued for 30 sec and it is stuck tight. good stuff. When I get back home I will tell you the name
