20 Gram IC-Gel Insta Cure Cyanoacrylate Gel
IC-Gel Insta Cure Cyanoacrylate Gel comes 20-gram tubes and is a widely used super glue within the hobby. With its quick dry time, and extra thick consistency you can use the IC-Gel on vertical surfaces and it will not run. It is great for heavier frags that you need to stand vertical or heavier rock work. IC-Gel comes in a tube like toothpaste which makes it very easy to dispense the amount needed, and when it comes down to the last few drops you can still get it out, unlike the harder plastic bottles.
Super glue (cyanoacrylate) is widely used for mounting coral frags to plugs, rocks, and what ever you may need to attach them to. Super glue can also be used to bond rock work when aquascaping for a seamless look. We find that if larger gaps are needed to be bridged when aquascaping either building up layers of glue, or placing a smaller rock that fits in the gap and then gluing over the top works really well. Usually when using super glue with aquascaping we will take a small amount of large grain sand to help give the glue some texture and blend it into the rock as well.
So long as the surface of the rocks are clean and free of debris/algae, this glue will stick just fine to wet rock. We've even used it for gluing under water, though you do have to be quick and you can't use the accelerator.
Have a great day!
You can utilize the Insta-Cure Cyanoacrylate super glue in an established reef tank without any issues. Some people do notice that different types of adhesives may cause their skimmer to go nutty for a few hours but your livestock should not be hindered in any way.
