I found this aragonite to be a lot cleaner than Caribsea, as well as having better pH buffering. It is quite fine, but that's perfect for my tank. Also reading on the bag, this is the official aragonite from the bahamas - they have a lease with the government there, so I don't know where caribsea are getting theirs...
