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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Everyone should have one for marine tank *by O***K on 22 April 2025* Brilliant ### ⭐⭐⭐⭐⭐ RED SEA REEF TEST KIT - VERy GOOD 100% Excelent *by N***C on 20 July 2013* RED SEA very good product.
