Glue for live rock

[vcnt]

I currently have a tank going, almost a month now and i am getting a 20 pounds order of live rock arriving friday from tampa bay saltwater to add onto my aquascape, what type of glue is best for these aplications where the rocks must stay wet? I used marco rock mortar for my other rocks but those was dry and i was able to leave them out of the warer to set

I use JB water weld epoxy sticks. You can roll it into a ball and put it between two rocks and squeeze down or even wedge chunks of it between two pieces of rock. It dries rock hard and just gives enough "structure" to keep things from toppling down. The rocks can still be removed from one another fairly easily if you want to.

How much is needed?
