CorAffix™ - Cyanoacrylate Adhesive

CorAffix is an ethyl cyanoacrylate bonding compound with viscosity similar to honey. Use it for attaching stony corals, gorgonians, and other sessile invertebrates in natural positions on the live rock in aquariums. Also for attaching coral “frags” in coral culturing. Use with AquaStik™ to attach larger coral heads. First put freshly mixed AquaStik on live rock. Push the coral base into the AquaStik and then remove the coral, leaving the impression of the coral base in the AquaStik left in place on the live rock. Allow the AquaStik to harden for 20 minutes. Next put CorAffix on the coral base and press it into the impression made in the AquaStik, forming a secure bond in 20 seconds. Available in a 2 oz bottle with an elongated tip that can be cut to the desired orifice size.

It's great

Pros: Fast stick, holds frags down well

Cons: Bottle nozzle clogs after every use but is easy to un clog

Once I found this glue, it ruined all other frag glues for me. It sticks fast and I don't have to hold frags on plugs for more than a few seconds before going in the tank. I highly recommend this product

Too thin

I usually purchase the larger bottle, but after having multiple bottles solidify before I used it all, I decided to get 6 small bottles. The first bottle of glue is very thin. It has no viscosity and drips right off the coral base. I'm hoping the next bottle is a much thicker (more viscous).

This works great to anchor dry rock before putting in your tank. I didn't find it easy to use underwater on coral. You basically have to smear it one both services with your hands to get it to work. Then as soon as you release the pressure on the bottle to stop the flow, saltwater enters and begins to react in the bottle. Epoxy has its issues as well, taking quite a while to harden enough to hold corals... Not sure which is easier..

For the most part this glue is good, it holds frags to plugs well. I will say that I have not had great success with it holding the plugs to rock work. But then again I have had less luck with the putty.

I'm impressed

Two little fishes keep delivering excellent products and the CorAffix is another example of one. The consistancy of the glue is almost honey like so its great for affixing zoanthids and sps frags to plugs. Just yesterday I 'affixed' a inch and a half sea fan frag to a plug and its holding tight. Saves me the trouble of using putty and covering up tissue to affix the frag. I even used the glue to cover a baby aptasia on a plug to kill it. Whats interesting is that my halloween hermit crab started eating the glue off the plug when I put it in the tank. Great product will buy in the future. And would not hesitate to recommend.
