Went to a frag swap yesterday and needed to glue my new frags to some of my bigger rocks in the tank. These rocks were too big to take out of the tank so I put some cyanoacrylate (CA or crazy glue) into a 1 cc syringe without the needle. I was able to apply the glue directly to the rocks in the water. I also put a small dab on the end of the frag and pressed it into the glue "blob". It worked perfectly. I was able to reuse the syringe by pulling off the glue from the end of the syringe ( wearing a glove ) and refill the syringe as needed. Try it.
