Yes read the threads. I use salifert for calcium reasonable price and accurate.Anybody here read the long threads other places bashing Hanna Calcium checkers?? The people complaining seem to have numbers way too high or way too low. Well, for me, Im getting API=340, HANNA=445. Numbers arent crazy like other peoples but still would like to know which one to believe. Wish there was a better way to be certain.
