Help please

I am upgrading my tank to a 75g. In my old tank i never needed to glue my rocks....but I do need to in this tank....Im so confused on what I should be using to glue my dry rock together for my new aquascape. When I Google it there are so many different responses that it makes it confusing. What glue can I use ? I do have some brand new gorilla gel glue.. Can I use it ?
Any help would be appreciated...thanks so much ☺

You are either going to:

1) Stack them carefully

2) Drill a hole and use an acrylic rod, zipties, etc, through holes in the rocks

3) Reef-safe cement/epoxy. There are tons of products. This is the 'glue' that you want to use, not super-glue, I don't think it'd be cost effective or very effective in the long run.

4.) http://www.reefsupplies.ca/online-store/AquaMaxx-Reef-Welder-Epoxy-Glue-250ML.html

I used #4. Essentially, you boil the pellets and they turn into a malleable ball. You smoosh some in while its still hot, and shove two rocks together and when it cools it forms hard. It lasts. You can reuse it if you manage to get it apart. If it doesn't set where you want it, just reheat it and its good to go again.
