## Questions & Answers

**Q: Recieved two bottles of A for the calcium test, how do I get a bottle of B?**
A: Some people I swear, you got a bottle of A and a bottle of B.

**Q: How accurate is this kit? Planning on switching from Salifert as I think this will reduce my costs some, seems easier to use with hand tool?**
A: According to the kit, the Calcium is +/- 5ppm, KH is +/- 0.05 meg/l and the Mg is +/-20 PPM.  Ive only had it a short time but I have found it to be accurate based on my tests.  I have verified dKH was very close to my Hanna tester.  I have only used 1 salifert kit and I can tell you the Titrator handle makes adding the titration fluid easy and quick.  Overall it makes the tests much easier to perform.

**Q: Is there a refill kit for these tests with just the Titrant’s and Reagent’s?**
A: Not with the one I bought.  But you can buy them with the refill kit or get them at Petco.

**Q: by other reviews, do these kits still contain the recalled calcium reagant? These are the faulty batch numbers. Thanks**
A: Stamped on the label of Calcium Reagent B, and compare it to the list of faulty batches: 1993, 2003, 2013, 2023, 2033, 2043, 2053, 2063, 2073, 2083, 2093, 2103, 2113, 2123, 2133.Those were the only batch's that were faulty.
