Foam Rock Wall & gorilla glue!

Same stuff as the foam itself. I used it about 5+ years ago to glue a large show sized rock back together after I broke it in about three pieces when I knocked it over in the driveway with the pressure washer. For a long time it looked like some yellow sponge on the rock, it's long since covered over, and holding strong.
 
I would not recommend or use gorilla glue in my aquarium. Just because you are running for a week means nothing.

As he quoted, As far as I can tell its reef safe. How do you tell? Are you testing for everything that it could possibly leech in your tank?

Is it worth saving a couple bucks on glue to risk thousands in a reef tank?
 
As far as I can tell it's been reef safe since the summer of 2007...

Notice the glue oozing from the large piece of rock...

It's a polyurethane glue that is moisture setting. There are minimal solvents and once the monomers are set they should be fairly stable. Gorilla claims their glue is water proof, even if it isn't, mechanical failure is far more likely than chemical failure.

Excellent first post. Thank you Sir.

I have also used this w/ some rock scaping before. Had the same rock for about 3 years. Never had any issues with it. I didn't allow mine to ooze out of the rock structure but it shouldn't matter. It's pretty strong stuff, I just prefer to use the emaco from emarco, as it looks more natural. it does work great for gluing broken pieces back together though.
 
The official word from the company is after its CURED its safe.

However I think you probably should have called and figured that out before putting something in your tank instead of doing it first then testing with fish and crossing your fingers. It amazes me (not picking just on you) how many people put/use things for their tank that they don't check out fully.

BTW The rock wall does look good, and hopefully it colors up nicely and works out
 
You are correct, it wasnt the smartest thing i have ever done. I more so did it to prove a point, and was willing to take that risk. Thanks everyone for your input i hope this helps all the other foam wall builders.

Alll it took was a bit of research to find that Great Stuff foam that people were already using, and Gorilla Glue were very similar. I had no intentions of going into it blind, and didn't.

Great stuff pond foam directly says safe for fish. Gorilla glue does not but has been verified inert after a proper 7 day cure.

Just because things have similar ingredients doesn't mean it's safe to use. Lots of candy uses ethylene glycol as an ingredient, your car also uses it as anti freeze..... Needless to say one is safe and the other is not.

I did this before "pond foam" was available, or at least not widely popular if it was. Many things we use don't say "reef safe" because they were never intended for the purpose, call Mrs. Wages and ask if their pickling lime is "reef safe", I'll bet they say, huh? The point is I made sure it was safe to my satisfaction before I used it, then passed my findings on to RC several years ago. Not everything has to specifically say "reef safe" to find a home in this hobby.
 
I understand, but i did let it cure for over 7 days. Once every turns out ok and i have tested it for a peirod of time, then can it be deemed "reef safe"? This is the main purpose for using gorilla glue in the first place, not many people are going to risk trying it. I did. I also want to share with my fellow reefers another cost saving opion.
 
This is a great thread. Not many people would have even considered using gorilla glue in their tank. But like what was suggested above a google search and call to the company would have confirmed that once cured the glue would be chemically inert. That's is a great +. I used it to glue egg crate to the back of my Cadlight aquarium a few years back. The stuff is kind of messy to work with and it does expand on a smaller scale but similar to spray foam. I didn't care for the yellow coloring of it but once it aged in the tank the little bit that didn't get covered with sand or rock purpled up. So although the question probably should have been asked before being used it was his choice to take that risk. On the other hand the topic itself is a good one in my opinion. Gorilla glue has many uses.
