what to use to attach corals to LR

[tektite]

I'd check that ultra gel for ingredients other than cyanoacrylate. For aquarium use, it needs to be 100% cyanoacrylate. The container says "rubber toughened formula", I'd be careful about using it.

I use the superglue gel for smaller frags and Knead it Aqua for the larger corals and rocks.

I find the Knead is good but does take a while to bond.

I use plain old Loc-Tite gel (i think it's called "control")... must be all cyanoacrylate like they have said...I have found it at WalMart and Michael's...

wow, this is cool beans. I did not think that there was a product you could use to attach frags and rocks together while they were in the aquarium.
(packing up now to find some cyanoacrylate super gel at the nearest home depot)
