Years ago when I was planning on gluing a lot of rock together for our 125g. I fell into bad health, but I'm now wanting to get back into the hobby. I watched a video on YouTube on a refer that used maybe,....baking soda, ??? And some other wet product, maybe superglue,..? that glued the rock very quickly, I wish I had better info ! It was dimple, fast and cheap.

Most the products that have been posted here are expensive unless using the Dollar Store super glue.

What about a glue like this ?

"The Vikings used pine pitch to seal their lapstrake long ships. They made trips from Scandinavia to the British Isles, France, and down the European rivers as far south as Byzantium. Not a bad track record, for pine sap !''. End quote...

It must have stood up to the ocean saltwater, so why not with our tank rock ?

I was trying to get spaces between the Dry Rock, so this meant less Contact area , some rocks as little as two places. That’s why I used pulverized Dry Rock, to fill in the gaps, at my contact areas. Some places have multiple glue layers, done after a twenty-four hour set time.

In my system I've used a tooon of different adhesives. Here's what I've learned...

When I resealed the tank (it was an older used tank), I used silicone, more specifically RTV 108 silicone. I 100% highly suggest this as it makes an incredibly strong adhesion to glass and is 100% silicone (and therefore 100% reefsafe). Let it cure atleast a week and your house will smell like vinegar the whole time.

For constructing rockwork, I used a combo of E-Marco mortar (reef safe) and 2 part epoxy. The mortar was great as it made a permanent bond between what it held, however support is necessary until it cures which takes a while. I actually drilled each of the main rocks in each stack and put 1/2" acrylic rods through them to help further with stability. My rocks that I did in the manner are (I suppose redundantly) "rock solid". I also used the 2 part epoxy to adhere various smaller pieces and also larger pieces I added later on in order to give a little more shape to the reef.

For frag adhesion, I use a combo of gel super glue and 2 part epoxy sticks. Knead the epoxy then super glue the frag base. Mold it to the base. Then glue the bottom of the epoxy ball and stick on the rock. Smaller things just get super glue. By in large this method has served me well.

All of this has been completely reef safe in my experience and a skimmer and carbon will pull whatever little compounds are released into the water.

Steve, could it have been you ? I remember pulverized rock, what did you use as glue ?

Would these be another option ?
And why can't we use aquarium sealant when joining rocks, will it not adhere to rock or it's not strong enough to hold the weight ?

I'm just researching products that will work great and at the lowest price possible.

When you see the term “mildew resistant”, it can be a yellow flag to suggest that it might not be aquarium safe.

I wouldn’t use Construction Adhesive, or Construction Caulk. The off Gasing is terrible, and the most likely contain UV and Mold inhibitors. I’ve used OSI Caulking, on Windows and Doors. I would never use it inside. Also it takes about a month to fully set in cool weather, it skims in a few hours. The set time, makes it last.

The absolute ultimate is the epoxy putty from PC Plumbing. it's NSF for potable water and cures underwater. seals leaks on pressurized lines and hardens like steel. you'll be amazed and want to have it around the house for anything to do with plumbing as well. or boats. or aquariums. on Amazon.

I've re-sealed two tanks using a Aquarium silicon---no issues with either. On a new build I've started (no thread -- yet) in the rock scape I've tried to use Super Glue (that failed miserably), Hot glue, (even more miserably), Gorilla Glue -- Failed, and marine epoxy -- ok so far.
