What glue works underwater.

[FishieBusiness]

Have used some cheap 2part stick epoxy. Cut and mix. But this is ugly to look at especially when it draws your eye away for the beautiful corals its holding in place. I used several different types of "Super Glue" but nothing seems to hold for long. Was watching the tank and saw a colony of Blue tort start to sway and then break free from the location that it had been attached for months

So what do you use to attach your coral to the aqua-scape??

For frags and small colony attachment to rocks I use

3 Pack IC-Gel Insta Cure Cyanoacrylate Gel Coral Glue .7oz / 20 g: Amazon.com: Industrial & Scientific

cyanoacrylate gel (superglue gel) definitely is the best imo. some dollar stores sell packs of them, but I've never seen them

A lot of guys swear by the gel from harbor freight. I got a huge bottle of ecotech gel glue for half off last year, you can literally build a 1 inch slump mound.

Super glue gel. For big jobs try Fauna Marin Aqua ScapeFix https://www.amazon.com/dp/B07C4RXZFY/ref=cm_sw_r_cp_api_i_DeNsEb4VYQQ3X
It’s a cool plastic that is malleable at temps above 110 and hardens once it cools.

They work really well and if you can’t get a frag to stay with the plastic stuff using superglue in conjunction with it works well too

The ic gel works good I usually just get the super glue gel at any store works fine. But I needs to be the gel

The Gels mentioned are the best for small coral colonies.

The 2 part epoxy, most of them finish in white color, are not ugly as you wrote. You just have to wait until they get the color of the stones (coraline algae o brownish etc). Just wait !! And in a couple of months it will be unnoticeable.

There are colonies that you will need those 2 parts epoxy to keep them in place.
