Over 20+ years, there were just over 2 years i didnt use IO, or Reef Crystals, I used RS Blue.Adding to the prior post, TM is in the middle of investigating multiple reports of issues from users seeing their salt mix brown (from German and Turkish batches), TM acknowledging some clay-like material, reports of coral issues, and TM voluntarily replacing Turkish-made salt buckets. I’ve been a user to TM for 3+ years but can’t justify the cost and quality concerns to pay such a premium any more. I found this thread very helpful and am starting a switch to Red Sea Blue bucket.
It worked fine. It does leave brown muck in the bucket, but that never seemed to bother anything. The reason I went back to Reef Crystals, was I didnt see a difference in results. RS salt is almost double the price of Reef Crystals, so I went back with my Ex. Same results but cost me a lot less .
