No one's listed my brand yet. I've been advised by a former TOTM recipient in a private message to use "any other salt but this one". I asked because I'd never heard of it. Although some claim that it bleached their corals and killed livestock, I continue to use it and my SPS, clams and fishes are not just living but thriving with no stresses at all. I've never bleached a coral as I was warned would be the most likely outcome. It's Crystal Sea Marine Mix.
I called Crystal Sea's parent company, Marine Enterprises International (MEI) in Baltimore to ask them why so many on reef boards malign their product, and the answer, although I'm paraphrasing, was this: When Dr. Shimek's study on salt mixes came out with regards to which ones would allow urchin embryos to thrive Crystal Sea came out on top. The belief was that heavy metal concentration and the use of EDTA (a water clarifying agent) in other salt mixes over time built up to toxic levels which eventually caused the dreaded "tank crash". Now I know why some people are so thrilled that their salt mix clears so quickly. Honestly, who cares? Are they trying to see how fast they can throw it in their tank? Many people read the study and rushed to buy Crystal Sea and proceeded to perform many massive water changes to rid their tanks of these impending toxic conditions. Obviously, doing this with any salt mix can wreak havoc on any established tank and is not advisable by any salt mix company. So thus, the Crystal Sea bashing began. Since these other brands learned of the study, EDTA is not as prevalent in salt mixes today as it was back in 2003.
Personally, I believe what I was told by MEI. I cycled my tank with Instant Ocean, ran out of that so I bought some Oceanic, ran out of that and started using Crystal Sea and haven't looked back. The only difference I've seen is there's more money in my pocket and I can do larger water changes, thereby keeping my tank in check easier. It costs $19.95 for a 150 gallon box. It consistently mixes to 9dKH and 380 Calcium. With all the SPS and clams in my tank I use a reactor anyway, so the lower numbers are actually welcomed. I feel a shift to the low end is better than one which throws alkalinity too high.
My point is....don't believe the hype. If you like a salt mix, go with it. We're really stressing over minutia here folks. What good would a $90 bucket of salt mix do for you if it makes you skimp on water changes and basic husbandry. I can have 600 gallons of water changes to that one hyped up $90 "pharmaceutical grade" bucket. Like other things in life, we need to "get back to the basics". It's usually the Indian, not the arrow. I'm not saying go out and buy Crystal Sea. Actually I could care less if anyone else agrees with me. If it's so horrible why does it mix to the same parameters every time I test it? If it's that bad, it's pretty damn consistent at doing it the same every time. After researching all the public aquariums and wholesalers who use it exclusively, I felt sort of weird stumbling across it simply on a price point. I've come to find out that my favorite not so lfs, The Hidden Reef in Levittown, PA uses it exclusively in all their fish, invert, soft, sps and LPS tanks....basically everything salt in their thousands of gallons of systems. And only $19.95 for 150 gallons. Hmmm. Go figure.
