Hi all, well things were going ok with my new saltmix trial until my third change, it was not so good

I did my third change with the salt yesterday and it finally happened
All my stony's completly closed up, my anemone, and some of my softies as well. I had the water mixing for 4 days in a pail with a 402 powerhead and a Optima air pump and stone cranked up before changing it. All perameters where the same:PH,Salinity,Temp,etc... I don't know why but also when I added the new water it did not disolve completley as it turned the tank cloudy. It took about two hours for everything to re-open and clear up. The Frogspawn and Montipora however took way longer-about six hours. And both my acro frags shed some serious mucus too
I don't know if I'm liking this new saltmix anymore

When I used IO I never experienced these kind of problems. I also see that there is a growing number of people responding to the thread on RC with the same troubles. I can only guess that MEI'S refinning process is not as good, this would explain the cloudyness and also the brick like form that it came in.
I have about half a box left, so I think my trial period will only be for a few more months and then I will make my decision as to sticking with the Crystal Sea or going back to Instant Ocean.
Cheers, Rich

P.S. Thanks Tony
