How to attached rocks already in tank?

[Jib]

When I built my aquascape, I thought some rocks I stacked were stable enough that they didn't need attached. They are stable, but I'm rethinking the decision. Is there anyway to attach the rocks now that they are already in the tank?

Timely post, same issue, only my stuff got critters on it.... I was thinking of the two pt epoxy sandwich: Super thick super glue 1st, then 2pt, then super glue on that.

lets both wait for a better explanation or method....

Personally, I try to superglue rock if possible

That’s what I do for rocks (and large frags), holds them pretty well. You can put superglue on both sides of the epoxy and submerge it in the tank, then lift your rocks up and fit it between them, then push them back into place.

Any recommendations for the epoxy?

Get the "Gel" super glue, I've had good luck withe the normal blue colored one you can get at most stores

Gel super glue - epoxy - gel super glue sandwich.
I used jb water weld for the epoxy and gorilla gel glue for the, well, gel glue.

I don’t find it really matters, since it’s primary purpose is to just fill the cracks so that the superglue can do its work.

I use this most of the time and have been pretty satisfied:Instant Ocean Holdfast Epoxy Stick Bonding Solution

This is the superglue I use: Gorilla Super Glue Gel XL, 25 gram, Clear, (Pack of 1)
