Adding and gluing rock to established tank

[bluecheese]

I want to attach this arch

To these two pieces of rock already in the tank

So that it looks like this

Suggestions on the best way to do this? The attachments points will be kind of small, so I don't have a lot of surface area to work with. I'm thinking of doing the superglue/putty/superglue method I use to attach frags, but I don't want to be sitting there holding the rock for an hour waiting for the putty to cure.

Superglue gel first into place so you don’t have to wait an hour.

Then add the epoxy for extra support and hide any super glue the next day.

I'll try it. I'm not sure if the superglue will be tough enough to hold the rock in place for a day though.

Only gorilla glue gel worked for me.
If it can’t balance itself with flow off, it’s not going to work.

Is there a specific Gorilla Glue to use, or is all their gel superglues reef safe?

The ones perfect and safe.

When you try, put a good amount on, hold under water in a bucket for 60 seconds, then stick together and hold.

Excellent. Thanks.

I got it in there with Gorilla Glue, and put some Aquastik on the top. Hopefully it holds over night. If so, I'll add more reef putty to it to get it locked tight on there.
