switching salt soon

Interesting. I never ever had any deposite with IO or Reef Crystal but always have had a brown deposite, sort of shiny, with H2O and I tried 3 buckets with the same result. After writing to DD they said it was due to ferric oxide they add...not exactly pure salt mix huh?

Don't you get that with RB? Sometimes I think weird readings can be bad test kits, bad batch of salt, or poor testing habits. Never know...

Hmm, haven't had that. However, ferric oxide is simply GFO minus the G. Ferric oxide is a fancy way to say rust. Not a big deal...however I'm not sure having the GFO mixed in the salt is really a good thing.

thanks everyone lots of good info here. I've also noticed some small flakes at the bottom of my mixing tub.

Yes, no big deal, but still not pure sea salt

However I am not sure what is the crystalic shiny deposite, as it is not ferric oxide. I use ferric oxyde and it is not shiny.
