What epoxy?

I've been googling but always sooo many different, conflicting answers. What 2part epoxy is good for underwater? The packaging says it's waterproof but not for use submerged (confuse much). There is marine, but again 'not for use submerged.' Some are for potable water and some aren't.

Which one is safe?

And lets stay away from the aquarium stuff, cause we all know its the same stuff but overpriced

Well, the potable water stuff would highly likely be fish safe. But would it hold under water?

That is the $8.99 question.

You need to check out "DIYJoey" on youtube. he makes all sorts of custom tanks and his videos are amazing. Real inspiration to the community. He talks about epoxies to use and which ones suck

I think they mean you can set the glue out of water, then you can immerse it and it will be water proof.

Oh and Ive also seen alot of cyanoacrylate (superglue) sold for fixing coral to rock, I used it on a couple of my custom tools I use in the water, doesnt seem to cause an issue

Yes, I would be using it dry, letting it cure out of water. The labels say 'not for prolonged immersion.'

I have cyanoacrylate (several different brands) but I've had issues with it not holding. As in, you bump an anubias rhizome and it comes free.

I don't plan on using epoxy for glueing plants, in case you're wondering.

Very strange that cyanoacrylate doesn't work for your purposes.

I've used both the regular type as well as the gel type with good results.

not sure what youre using it for since you didnt say. i had a situation with my dishwasher,
a piece of plastic cookware fell onto the heating element and melted around it and in on the
brace. while i was scraping the melted plastic i ripped up the brace bolt and all. i used:
http://www.loctiteproducts.com/p/epx...oxy-Marine.htm
to basically fill the hold and attach the brace. after i gave it the appropriate amount of time
to cure, gave it a test run, and no problems at all. had it like that for several years.
