Used between the driftwood and the rock then molded some over the driftwood branch to the rest of the epoxy on the rock. Let it cure for a few days. To the touch it was very dry and turned all white. As soon I picked up the rock it all fell apart. All pieces of epoxy could obviously not be used again. Super disappointing. Next time I’ll stick to glue and silicone

Jim johnson: I was building a gravity defying aqua scape but it broke at the base, the actual rock broke in half, the epoxy was stronger

Cheryl Bederski: Held up enough to get it into the tank, but fell apart to move larger heavier dry rock. Worked like putty and set fairly quick but not too quick to get it into place.

Callie: Bought two of these little tubes to "cement" my rockwork together in my saltwater tank and used about a tube an a half. I had about 120 pounds of rock that I wanted to form into a few structures in my 75 gallon tank and this stuff worked beautifully! I had been letting my rock cure in large tubs with a circulation pump for a few weeks, so they were still very wet when I used this epoxy to hold them together and it still became rock hard and my structure is SO sturdy. I created a large archway and a complete hollow circle through the rocks. Neither of these are very sturdy structure alone, but with the epoxy I could grab the center of the archway and pick it up with no breaking and no worries. I would absolutely use this product again if I ever need to do another aquascape. It dries stark white, but will soon enough be covered by beautiful coralline algae, so no worries.
A few notes:
-This is NOT glue. It is NOT sticky. It will NOT "hold" two pieces of rock together. You cannot simply plop a piece of this epoxy on the bottom rock and shove your other rock on top and expect it to hold. It will NOT hold. I found the best way to ensure a sound structure was to position the two...

N. Hanks: I used this on dry slate rocks prior to putting them in my aquarium, and it holds pretty well. A small amount of this glue will hold things together - I used maybe 1/5 of the stick to glue together about 15 slate rocks into a bridge formation, by just putting a small piece (maybe half the size of a piece of gum) between the rocks. It was easy to use, kinda gross on my hands but washed off within less than a day.
Note that it is not supposed to be applied while items are submerged in water or wet. This glue stick is intended for use on dry items, so if you're trying to glue coral, do not try to use this - your coral will die while you're drying them out.

HannahrainHannahrain: I use this to secure my dry rock together when creating a reef aquascape and also for attaching frags. When attaching frags to live rock, you must add superglue gel to both the epoxy side and the live rock side of the epoxy. You basically sandwich the epoxy between superglue gel or it's not going to adhere correctly. It's aggravating at first but if you continue to attach your frags this way you will get better at it. I find when the epoxy is used in water never gets totally hard but stays somewhat gummy. However when used on dry rock and allowed to cure for 24 hours it becomes rock hard. I had to remove a rock from another after 24 hours and it took me beating the rock with a hammer to get the cured epoxy to break. I've also let balls of just epoxy dry accidentally and they next days they are basically rocks themselves.
Tips for aquascaping with dry rock: use the little broken pieces from the rock to stick into the epoxy joints you make to help hide the epoxy. Do this under 10 min or so or it will be too hard by then. On rocks that just aren't stable enough and want to roll, you can add little "feet" that stabilize the rock, to keep the "feet" from sticking to the surface...

JMH: I've used a bunch of others and find the Instant Ocean epoxy the best for the money. Sets strong but doesn't set up too quick, always consistent.
