3 Pack IC-Gel Insta Cure Cyanoacrylate Gel Coral Glue .7oz / 20 g

I use this for crafts, great value!

Great - a thick superglue that works!

Been using this same gel for many, many years in the reading hobby. It is a really good glue. Let it set up outside the tank for a minute before going in the water. Once you get the hang of it you'll grow to love bsi. Everyone tries many glues in the reef hobby and this is the best I have found in the last 12 years and I have used many types of glue. Rule one is go slow and be patient when gluing a new frag. I am eating the glue a four but giving five stars due to the discounted price the company sells it to the reef hobbyists. Most glues or products in the reef industry automatically charge higher prices because it is for the reef, ridiculous. Thank you bsi for caring about the customer. I am certainly loyal to your brand for the service you guys have provided.

This would be a review saying that the glue is not extraordinary, but does the job. It would earn 5 stars, but 2 of the 3 tubes I got are now garbage after using very little from each. When you squeeze the tube to use the glue, rather than come out through the opening where the cap goes, it uncurls the ends that are supposed to be sealed, and glue comes squirting out the back, all over your table or floors or whatever else you're working near. The first order of these, which I ended up giving to a friend to use for an aquascaping project, also had this issue. The first time it happens, you will think it's something you did. After the third time, however, you're just going to be annoyed that the manufacturer doesn't fix this already.

The best glue you will find for gluing rocks and frags in your aquarium. I've tried many in my 10 years of reefing and always regret using anything else. I've found it best to use multiple smaller beads of glue instead of one large glob. It cures faster that way and is stronger. When used properly, the frag won't be able to be removed by aquarium inhabitants but isn't too difficult to remove and replace the frag yourself when you want to. I have even recently started using this directly in the water to secure base rock and it works wonderfully - just be sure to wipe the tip off with a paper towel after so it doesn't clog for the next use. If it does get clogged because of this or any other reason though, each tube comes with an extra tip that comes in handy.

As advertised, you can glue things even when wet. We glued dozens of coral samples to waterproof paper in an experiment. The paper is a little slick and everything was wet, but it worked well. You just need a small area that's not too "pointy" for the glue to work with.

I've used a crap ton of different glues for my salt water tank either for rock or frags or whatever and none compare to this. I steered away from it in the past, but once I tried it I was sold. The thickness keeps it from spreading and makes it easier to keep frags in place while it completely dries. Super hold, so try to avoid getting it on your fingers.

Over rated does not hold frags good at all
