Which JB weld is reef safe?

[Frtdrmrose7]

is it JB weld Marine or JB weld water people have used in their tanks? I have a small crack in the cover for my reactor pump and it causes a hissing sound. I just thought I’d cover it up.

I used water weld to glue frag plugs down.

Yup! JB Waterweld is what I use as well.

It makes a thick putty. Getting it to stick to plastic might be difficult.
