HoldFast Epoxy Stick 4 oz
I prefer this epoxy over the red and grey. The red gets really HOT and dries way too fast. The grey needs a bit more time to cure than my fish will allow before they start plowing at the newly affixed arrival. This dries white and will color up over time just like your rock. The set time is perfect for my applications which is usually setting a plug in place. Once in a while I will use it to add rock to rock.

This stuff is amazing! . HoldFast Epoxy, by Instant Ocean, has a good solid consistency and sets in about seven minutes. Best of all, none of my corals have fallen down! I've used similar products in the past that cost nearly twice the price for the same amount. They take longer to set under water and they are very frustrating when they fail. I'll never go back to them again!

I used this to glue a few frags down and fit some loose rocks together. As stated works underwater as well. Never had any issues with it leaching off any toxins. Never lost anything while using. Dries rock hard in an hour outside of water. Inside water didnt seem to work but after a day or so it was hard. I highly recomend and have used a few times now.

It works just as promised. Yes, even underwater! It appears to not adhere at first but keep the item in place and you'll be amazed at how well it holds once it cures.
