JB Waterweld Reef Safe?

[ETORRES477]

I have read on other forums that this is reef safe. It says it is safe for use on potable water systems. Anyone have any information or experience with it. I want to mount a torch that has been mounted (multiple times) with super glue, but one of my Mexican Turbos must be knocking it down at night so I wanted to go with something stronger. Any help would be appreciated.

Yes I've used it with no problems

Thanks for the info!

Alittle trick with waterweld. It doesn't stick great underwater so put a alittle super glue on both sides and it will help stick until the waterweld cures.

Mat.. great tip! I'll try that

I've used it with no problems. I did turn off the skimmer for an hour or two until it hardened.

I have never had any luck with it holding any better than superglue

 

[gojk]

I put superglue on the top and bottom of it(coral side and rock side) and it holds really good. Just give it a little twist when you are pressing it into the rock and hold it there for a few seconds. The twist breaks the surface of the superglue so it holds better.

I'd stick to aquastick or some other reef putty.

I've used aqua mend for years with no problems. I just picked up 2 more tubes last weekend :)

used it for years, no leaching, no problem other than the mess it leaves on your rocks if you need to move the coral. I say avoid it for looks simply because buying superglue gel is better if you know how to use it. I hope someone has talked about this somewhere before if not I can make a thread all about the difference in adhesives. But anyway its how you use the superglue gel that makes it better in my experience and opinion for both looks and convenience.

"In general, cyanoacrylate is an acrylic resin that rapidly polymerises in the presence of water (specifically hydroxide ions), forming long, strong chains, joining the bonded surfaces together. Because the presence of moisture causes the glue to set, exposure to normal levels of humidity in the air causes a thin skin to start to form within seconds, which very greatly slows the reaction. Because of this cyanoacrylate is applied thinly, to ensure that the reaction proceeds rapidly and a strong bond is formed within a reasonable time."

In other words super glue gel or cyanoacrylate is a fast acting glue when exposed to water, however if you don't twist and turn the coral a little while trying to adhere it to a rock it will set up crappy and unstable and fall. The twisting and turning allows the outer "shell" of polycarbons to be broken forcing the chain in alternate directions (making the glue adhere super fast when underwater). So glob that superglue gel, I get mine from the dollar tree, on the coral or frag plug then twist away until you feel a pull, next half a turn and you wont be moving that coral unless you want to.

just my long winded explanation and opinion hope it helped even if it was a bit off topic.

I like long winded explanations, those are the ones that help the most. If you and Gojk did not let clue me on to the twist part of mounting with superglue, I would still be picking that dang torch up from the sand bed every morning. Much appreciated friends.

Always better to get a thorough understanding of something than just a yes or know answer. Great explanation. Thanks. Appreciate it.
