Fixing rock underwater

[Dan7575]

So when I set the tank up I basically balanced the rock work and let the pieces naturally lock together. I’m worried now though that it may cause a disaster in the future as I add more coral to them. They haven’t moved in 18 months but I’m wondering if there is a way to fix them together whilst underwater?

Add more to stabilize or if its loaded w livestock its going to be difficult to “move” them... would have to putty them together while underwater

 

[Dan7575]

What putty would you use to do it?

 

[Acskippy]

Check BRS... they have a bunch. I dont remember mine but ive used it before.

Yup, you can use small rock frags with Gorilla Glue Gel, or Coral Affix Glue.
I put some glue on the rock frags and wedged them in areas to add support/balance.
You can also use underwater expoxy in a stick and coralline colour form to do the same.
(If you use expoxy, turn your skimmer off for 48hours.)

I just did this myselft, used Tunze Coral Gum.
I loved my aquascape, but had a few avalanches when doing maintenance. Went ahead and got the coral gum to stick them all together. My only regret is that I didn't get it back exactly like it was before...
