Glueing rock together with what?

[loans_n_fishes]

Do you have to wait for the underwater epoxy, grout, "plumbers buddy" and the like to cure before adding live stuff, or is it already reef safe? My tank is 32" tall, so the pvc stand is pretty interesting to me.

I put my rocks together in my nano with Gorilla Glue. It expands, runs, takes about an hour to cure and doesn't look pretty at first. But in no time it changed colors and blended in perfectly. It's pretty permanent though.

... with Gorilla Glue...

Really? I had thought about using that, but wasn't sure if I would trust it in the tank. No adverse effects? How long has it been running with the Gorilla Glue? I love that stuff for my wood projects.

About 6 months ago. If I remember right, it's a cyanoacrylate. A form of super glue.

Ive been building rock structures for my 180g using old plastic hangers cut into peices for rods and silicone. Same silcone we use to seal our tanks. they are coming out to be pretty good so far. The silicone dries and swells holding everything together plus I drill a hole just big enough for the rod.

I will try and get a pic.

I didn't think of using the silicone, but I purchased acrylic rods from Regal Plastics, they come in 6 foot pieces.

I went glue less as well with the threaded nylon rods and nuts

You can pick the whole thing up in one piece without worrying about stuff slipping. I've attached some new pieces to the side that wouldn't have held without glue or nuts.

Heres what i made using old Plastic hangers and silicone. Most of these have a tower look, but there are going to be placed in the tank to give it a more natural reef like look with the various cave here in there. Have to make sure my moray eel is going to be happy! also plan on making a arch.
