Like RR said, the ionic balance between Alk and CA is a bit off with IO (CA low but Alk high) but it is easily corrected by adding calcium chloride. I do this until I achieve my balance between CA and Alk.

Yes, I know, that it should come adjusted before hand, but I like this salt so much that I can live it.

Not trying to push any salt brand here, but thought you might like to know, one of the problems with coralife is the use of borate rather than carbonate for the alk, also check the MG, I was told one time that the "faster" dissolving salts are typically lacking in MG (not sure if that is true or not) and my TM has mixed crystal clear within about 30 min each time I've mixed it.
I know you are not trying to push salt brands, and yes it is possible, that they may use Calcium Borate instead of Calcium Carbonate as the buffering agent. As far as chemical compounds go, they are very similar in nature except that the Borate is far more dense in its structure than carbonates and is supposed to not precipitate as fast? go figure.. I thought that Borate was a poison... anyway, I emailed ESU to find out what they use as the buffer, and hope to get an answer soon... The Magnesium content seems to be fine, I would sayit looks like around 1200ppm when first mixed..

As far as the TM salt and the cloudiness, this was experienced with two seperate boxes from two seperate LFS.. All water was cloudy after mixing and remained that way even after 24 hours. It was only after putting it in the tank ( I think you remember me complaining about this in other posts ). when I asked you if it would be ok to use it anyway I took your advice and used it... I got no illl effects from it, it was just freaky... I didn't like the way it clouded, so I gave it up...after 50 gals of water changes...LOL...

I am going to wait to see what it is ESU is using if they will tell me, and then I may think about making a decision on which salt to use...

Calcium borate may be similar, but it artificially raises alkalinity, and ph issues tend to follow.

I do understand the concerns with the levels found with IO mixing. Mine always seems to mix consistently to 400ppm Ca, and 5 dKH (loganj - did you mean dKH rather than meq/l?).

Anyway, I don't really look to my salt to provided consistent ca/alk. The only thing I want my salt to do is make my water, well, sallty. I think it's because we change so relatively little water (10% monthly), that it doesn't seem to impact our parameters all that much.

If you're changing a higher percentage of water at a time, then yeah, I'd probably look for something that wasn't going to skew my tank levels.

Ok, jut to let you know, I received an email from ESU today about whether or not they used Borate or Carbonate in Coralife salt and the answer was:

Dear timbo2,

Thank you for your interest in our Coralife salt. Our salt does not have borate but does have Sodium Bicarbonate in it. Also, the calcium in our salt is derived from Calcium Chloride.

Steve M.
