Review on 🐠 Fish Safe Instant Ocean HoldFast Epoxy Stick (HF-1) - 4USoz./113g by Kristin Morris

I bought two of these tubes to "glue" the masonry in a marine aquarium and used about a tube and a half. I had about 120 pounds of rock that I wanted to shape into multiple structures in my 75 gallon tank and this stuff worked great! I left my rocks in big circulating pump baths for weeks so they were still very wet when I used this epoxy to hold them together and it still came out rock hard and my structure is SO solid. I created a large arch and a complete hollow circle in the rock. Neither is a very strong structure on its own, but with epoxy I could grab the center of the arch and lift it without breaking or worrying. I will definitely use this product again if I ever need a different aquascape. It dries completely white, but soon enough will be covered in beautiful coralline algae, so don't worry. A few notes: - This is NOT glue. It is NOT sticky. It will NOT hold two boulders together. You can't just smack a piece of this epoxy onto the bottom brick and slide another brick on top and expect it to hold. WILL NOT last. I've found that the best way to create a solid structure is to position two pieces of stone exactly how I wanted them and then completely surround the seam of the two pieces with this epoxy, being careful not to stuff as much as possible into the nooks and crannies on each. piece of stone as I went around and then smoothed out a bit of epoxy on the sides of each piece of stone. This works best if already without the epoxy the two pieces of stone can stay balanced without moving. Otherwise you just have to hold them until the epoxy starts to harden. Keep a cup of water nearby while you work. While mixing the epoxy, dip a finger or two in the water and keep working. A small amount of water helps mix it much easier and faster and softens it up a bit so you can get into the nooks and crannies of each stone better. When you've mixed the epoxy and are ready to apply it to the stone, dip a finger or two back into the water. Use these fingers to work the epoxy on the stone. This will help the epoxy adhere to the stone instead of your fingers and will allow you to smooth it around the stone pieces and into nooks and crannies. Allow the epoxy to cure for a few days before moving the stone or submerging it in water. I let mine cure for about 35 hours before doing anything about it. I really wanted to keep my stones wet so I occasionally sprayed them with some salt water and it didn't seem to ruin the epoxy at all but I would be careful not to submerge them too soon. I know it's been a long time but I wanted you to have an honest review and some helpful tips! I hope this helped you!
