Started stripping my sump and came across this.

None of the silicone in the display tank is blue so should I just make a new sump?

If I pull the silicone apart it is blue all the way through. Can copper do that?

Copper is the most likely suspect, can you strip the silicone and redo it?

Ok, just phoned the chap I got it from, he says its from the water conditioner and guarantees me no copper was ever used? What you think?

What water conditioner was used?

 

[Mekaeel]

even if it was copper that was used,its merely the dye that has remained on the silicone,after a wash,it is reef safe.talking from experience,as i converted an old copper tank sometime back into a reef tank with no ill effects.

I know some of the white-spot treatments can discolour the silicone to a bluish colour.

Looks like something I have used in FW Methylate Blue when I was younger, silicone went Blue, will have to ask Palmaer or Midasblennie whats in that

 

[gaboon]

Thanks, will give it a good wash. He said it was a tetra product, not sure which one

 

[Alan]

Water conditioners, medications, copper can all discolour silicone.

 

[gaboon]

Good to know, I though only copper could do this

 

[Mekaeel]

and also remember that by washing it,it wouldnt remove the blue,but it will be safe to use

Most likely methylene blue was an ingredient in the conditioner, no worries.
