Gluing/Connecting live rock

[drstevemiller]

Hi All
I have a 320 gallon tank that I'm going to set up that I bought and all of the live rock is inert as the tank was broken down. Most of the rock would look OK in a 55 gallon but in this large tank the pieces look like pebbles. I would like to glue/screw the rocks together but I'm not sure how to do it. Has anyone connected live rock together to make larger pieces? If so how did you do it? What glues/compounds are safe to use?
THanks, Steve

what i did was drill holes in my rock and stacked them on those acrylic curtain rods which were apoxied to a pvc frame which rests on the bottom of the tank. to get pieces to stay togeather that were not on the structure i drilled smaller holes in the rock and used short pieces of the same rod to connect the rocks.

What bit did you use to drill the rock?

I'm curious about this too. What can be used for gluing live rock? Can anything be used underwater?

Look for Marine safe epoxy on some of the web marine retailers. They even have some hte drys to look like coraline algae. Most of these you can also use underwater. The other option that works well is black silicon (sold at pond supply stores)

I saw a few reefers with large tanks used this stuff for the back wall.
