Is this adhesive reef safe?

[flat6guy]

I'm looking to bond my dry rock together. Does anyone know if JB weld's marine weld or JB weld's water weld is reef safe? I attached pics of the back panels of both of these products to assist in this question.

I wouldn't use it, but that's me. There's a lot of reef safe epoxies out there. Heck, I used quikrete hydraulic cement on my dry rock when I did my latest build. Works well.

Take a look at bulk reef supply and see what they have

Ordinarily, I would probably not use that, but it does say that it is safe for use with potable water. So, it may be fine. Maybe someone that has actually used it will chime in. I would make sure that it was fully cured before putting it in the tank though.

I've used water weld for years. Its the same as instant ocean hold fast with a different dye in the outer epoxy.

One can usually get the hold fast on amazon for 6.99 but it's twice as much as the waterweld which is usually 5 and change for the smaller.
