I'm having the same issue as well. I've used TM pro for 2 years now, and almost a full year in my new mixing station (45 gal brutes).Does anyone know if TM changed the 'recipe' for Pro Reef? I have used the salt for a while and mixed in a white bucket with never any residue. I am now on a new bucket and I am getting a coating of brown gunk on all surfaces of the bucket and on the mixing pump. I can even see the water has a brown/orange tint to it once the salt dissolves.
The newest bucket of salt I got started developing the brown buildup within the first day.
I was going to preemptively change filters and resin on my RODI thinking that had something to do with it (though TDS still 0) but glad to hear others are seeing the same issue!
