Fixing dry rock to back wall?

[Fasthandsslowmind]

I've got an established tank and am making a few small changes to my Aquascape. Just a little progression.

I'd like to glue a small chunk of branch rock to the overflow wall (It's a peninsula) to look like about 6-8" of branch rock is growing out of the glass.

Has anyone had any luck with getting an overhanging rock to actually stick to the back glass? If so, how?

Thanks!

Ooo this could be cool!

I assume your doing this while the tank has water in it and the water level would be above where you want to attach the branch?

Its doable. Best advice is to cut the branch rock on one side to make it flat so you have enough surface area for it to adhere to.

Can you use magnets and glue that to the surface of rock? Ive seen magnetic frag rocks made like this.

That's gonna be tough to do when considering leverage. But if it were me, I'd probably consider draining the tank down to the level you want to attach to rock and make sure it's dry, use a good 2 part epoxy and get the attachment point of the rock as flat as you can. Probably need to rig up some sort of support until the epoxy cures as well.

Just an idea... if you cant drain the tank to the level needed as mentioned above, you may be able to set up a harness type system with fishing line or something to support the majority of the weight until the adhesive you use cures against the glass

What adhesive should I use? Can 2 part epoxy be used underwater?

For sure I’ll have to brace it while it cures.

There are a number of epoxies that cure underwater. But the challenge is getting it to stick to the glass. Maybe rough the surface slightly with fine sandpaper...but epoxy and glass is risky ime

It is doable. Just take every percaution.
