There are many reef safe glues available. When I did my rockwork I used Instant Oceans 2 part epoxy glue.

I’ve always used thin superglue and either rock dust or baking soda. Either forms an incredibly strong bond.

This is how I have done mine. I used marco rock and the marco rock powder and thin super glue. For the most part the "weld" is stronger than the rock itself. Next time I will probably add in some Marco 400 putty(?), just to help reinforce the rock and "weld" area.

Dowels and epoxy.

Portland Cemented mine. Didn't fancy a rock avalanche like in my old tank.

JB weld works perfectly. It's cheaper than aquarium epoxy, dries quicker, and dries harder.

use Cyanoacrylate liquid glue from loctite (the super thin runny kind) what I like to do is pour sand between the two rocks and then saturate the sand with glue, repeat a few times and you'll have a super strong rockscape, it works way better than epoxy and is my preferred method. I've done it with all my tanks and have had good results.

I have used Marco rock aquascaping mortar in the past, forms a very strong bond however can be tricky to work with as it isn't sticky and needs to sit perfectly still for 24-48 hours to fully cure, though good for heavy duty holds with 10+ pound rocks IME. you can also use a mixture of epoxy putty and glue, but I like to find a way to stack the rocks firmly without glue as it's honestly much easier
