Bpb Posted September 24, 2013 Share Posted September 24, 2013 Anyone else order a new reagent "b" for their Red Sea pro calcium testers? Mine came in today. Odd...it's the same lot number as the recalled ones, but a different expiration date. I still have the bad one as well. Gonna test my calcium with my old reagents, recalled one, and the new one and ill post results tomorrow. Tested a sample of someone else's tank water today with my old Red Sea pro calcium kit and an API tester and the results were about 200-250 ppm off. That's a pretty significant margin.
