Glad you are happy with the Koralia pumps. I use different glues for different corals. I use the Super Glue Gel for most stoneys but now and then the SGG just won't do in certain situations, like a big
frag. Then I use the 2 part epoxy putty. Cut off what you need, mix it together and stick it to the rock and push the base of the coral into it. work the putty up around the base a bit and it should hold. It sets up under water just fine. You can get it at
HD or Lowes in the plumbing department. Be careful, ask for 2 part epoxy and not plumbers putty. Two very different products.
Say good night, Lori.
