I recently tried out the Aquamedic salt. At first I wasn't happy with it because my tank was cloudy for a few days (new tank/new water/new salt--not setup) When it cleared I tested it, and I was very happy with the Ca and alk. They were right where I wanted them to be, and higher than any of the other salts I had tried (ocean pure, ocean pure pro, biosea). I haven't noticed any cloudiness in my wc water. Might just stick with the AM salt.
I haven't tested wc water in a while but I think the test was something like 8dKH and 420-470 Ca (can't remember, lol)
