Does waterweld by jb weld leach into tank or become reef toxic.

Should i be using it i need to add it to my pump to make it tight thanks

I use it regularly. If you do more than a couple frags it can make skimmer go a little nuts.

 

[zapbap99]

no im not using it on frags im using it on attaching plastic piece to my sump pumo

 

[tripdad]

Effect will be the same, it's still in your water. Nevertheless it should be fine.

 

[zapbap99]

yea just didnt know if it was super strong i mean i know it hardens like a plastic i thought so i might try it

 

[Billdogg]

I doubt very much that it will work for what you need. I'd try PVC/ABS cement.

I believe @happyhourhero has used this in his tank. I bought a pack, opened one tube, gave it a sniff, and decided I'd never use that in my tank. I suppose it's possible I got the wrong JB weld since there are several versions out there, but the one I got had a strong solvent odor to it.

JB waterweld is reef safe and will cure against plastic pretty well - Anything you can do with pvc cement out of the water will be better though.

If you have jb waterweld it's reef safe.

I actually was told to buy JB Marine Weld which I WOULD NOT put in my tank. Water...marine...same difference, right? NOPE

 

[happyhourhero]

I have used this for years.

If JB WW isn't reef safe then my corals and fish never got the memo. I've lost count of just how many tubes I've bought over the years. I consider it to be one of the "must haves" in my emergency aquarium kit. That, and as many tubes of superglue gel I can get at the $1 store.

Been using it for several years with 0 issues. It's the same 2 part epoxy most manufacturers sell as "coral epoxy", but for much less.
