Frag plug turning orange

jorge0912 · Mar 13, 2020

So I notice that some of my frag plugs are turning orange which is weird is that normal has this happened to anyone ?

I’ve never had that happen. Do you use RODI water?

could be iron in plugs??

I've had a few change to an orange color that where under glue. So when I would take a frag off the orange color would be where the frag and super glue was.

Been thinking about this for years Haha! Noone seems to have an idea but the orange color could only seem to be iron related.

Funny thing is, iron was my first hunch too.

Think it's time for someone to figure this stuff out. Maybe put it under the scope. I've always been so curious to what it was.

Could be from bacteria?

I have always assumed it was algae, or something in the glue that turns color in salt water.

Is it bad ? Has anyone had problems after seeing this in their tank ?

Happens to me too when I remove frags from a plug that were superglued. Not sure if it’s an issue or not

Is the plug magnetic at all? That should tell you if iron is present or not, imo. Might need a strong magnet if the iron content is low. Looks to be iron stains to me as well.
