Gluing Rocks

[brians_224]

Thanks for your time.

I have some small baseball sized dry rock that I'd like to glue together to form larger rocks. Can anyone recommend a method to accomplish this? Aquamend epoxy? The rock is very pourous - not sure if I can drill into it or not.

Epoxy would work.

I've found Hold Fast works great for bonding rock to rock, or rock to glass. From www.marineland.com Search for holdfast

Epoxy does work, but if you bang or drop the structure they will break apart again, so be gentle.

I recently used HoldFast epoxy to attach LR. I used about 1.5 sticks--my skimmer went nuts for a week. It works, but not all of the rock stuck. If the rock is still dry, glue it first, then put the assembled piece in the tank. R
