What do I use to secure rocks and corals together

I'm near building my aquascape and would like to secure the rock. What can I use to do that? Also, once I add coral, how do I secure them to the rock?
 
Just use reef safe epoxy you can get it at most fish stores or online.

I used Paleo Bond from Bulk Feef Supply. It is called Jurassic Gel PB4540. Its like a gel Crazy Glue, it sets relatively fast and dries clear. I love it.

I am also going to use a drop to secure my frags when I get to that point. A drop will be enough to secure them but not to much in the event I want to move them.

I'm with mcgyvr. I use nothing but gravity for the rocks. Superglue gel/ JB Waterweld for frags
 
I also like gravity in the event you want to move the rocks for whatever reason. Sometimes it just to maybe increase flow to a certain area.
 
Many don't recommend large structures for legitimate reasons, but I personally love using hydrolic cement to help make structures. I've made some really cool stuff with it it will dry enough to hold structure in a couple minutes and while drying, you can make impressions in the cement to accommodate frag plugs. Just worth the thought.

I used an epoxy from 2 Little Fishies to aquascape my rocks and I use the AF Poly glue for corals - i just used it for the first time last night; i liked it.
 
I have used reef epoxy, cyanoacrylate gel (super glue gel), zip ties, and fiberglass rods that are supposed to be arrow blanks because you can find them for cheap.

The epoxies and glues do not seem to work well on their own. I recommend using a glob of superglue on each rock to be joined with a glob of epoxy in the middle. That gives me the best results.

You can make large tower type structures by drilling a hole in a large heavy rock and inserting a rod into it and then using that rod to form a structure by drilling through other rocks and stacking or by zip-tying rocks to it.
 
Gravity, friction and the shape of the rocks 'locking' together.

I like messing with the corals and rock structure over time and 'gluing' them together just wouldn't work for me.
 
Actually scratch that previous comment I thought we were talking about rocks together. I always used superglue gell for corals. Little blue bottle. Keep it off your skin
 
Some folks cement their reef rocks together, which I always thought to be a really bad idea. I'm largely with the friction folks. Assemble your rocks so that they are stable; a few strategically placed blobs of epoxy putty keeps things together.
 
Occasionally I need to use epoxy to obtain a certain shape, like a tall and narrow structure but mostly just friction. Like others have said aquascaping is a perpetual work in progress so being able to move things is critical.
