Loctite Superglue gel question

[vic622]

So I read a few posts about using Loctite Superglue gel to mount frags to live rock. Picked some up today, put a big glob on the bottom of the frag plug and right away put it in the water and before I could place it on the rock (2" below the waterline), it had gone white and hard and wouldn't mold or stick to the rock.
Help! What am I doing wrong?

the glue dries instantly under water! You have to mount out of the water then place it in.

I thought I had read that you could go frag>gel>epoxy>gel>rock, so this way you didn't need to have the epoxy curing in the tank.
My wrecking crew - Turbos - have already bulldozed 2 frags off their perches last night, so I need something to hold them in place until they're established.
On this frag, I didn't need the epoxy, so I thought I'd go direct, frag>gel>rock.
How do you affix to the rock if you can't use gel glue?
Use Epoxy & let it cure in the tank?

I have only used it to directly attach a coral to a plug or a small rock piece out of the water. I think you need to use epoxy attach the plug to a rock already inside the tank as you found out it cures super fast under water. If the rock can be removed from the tank for a minute you could attach it that way with CA glue. By the way, if buy a little spray bottle of kicker (accelerant) it will instantly cure your glue out of the water as well so the coral spends as little time out of the water as possible.

I use epoxy to attach under the water.... but it doesn't work all that well as it still takes along time to fully cure.

What brand of epoxy?

D-D nothing wrong with it just takes a while to cure.

If you go frag>gel>rock directly under water, it won't stick well. I've used frag>gel>epoxyPUTTY>gel>rock and it has worked very well.

What I do is -

* turn off power heads, or anything that moves water
* get epoxy putty mixed and ready, small amount
* add a drop or few of superglue gel on the frag mount (flat bottom, not those frag rack mount)
* put the putty on the frag where the glue is
* put drops of superglue gel on the putty
* mount the frag>gel>putty>gel onto a rock, firmly press it down
* give it few minutes for gel and epoxy putty to cure

The aquarium safe epoxy putty cures within minutes after mixing, so you want to do this fairly quickly, and one frag at a time.

The idea is to provide best possible contact surface for superglue gel by using still soft epoxy putty. If you use the superglue gel only, it will be very difficult to achieve the same amount of bonding..

I'll give that a try, today.
The wrecking crew was out again last night, so I really need to get the frags secured.
Last night, using a flashlight, I discovered another hitchhiker, some sort of crab that was hiding in a crevice in the live rock. All I saw were some ~1" legs backing into the rock - add one more member to the bulldozer dept.

I put a large blob on the frag and when it is placed in the water it hardens the outside but not the inside.
I put the frag where I want it and give it a few twists which breaks the skimmed seal, and hold it in place about 3 minutes. It almost always takes the first time.
