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. ## Frequently Bought Together - Red Sea Reef Foundation Test Kit - Calcium, Alkalinity & Magnesium - Red Sea Fish Pharm ARE21525 Marine Care Test Kit for Aquarium --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/1627402-red-sea-reef-foundation-pro-test-kit-accurate-calcium-alkalinity](https://www.desertcart.hr/products/1627402-red-sea-reef-foundation-pro-test-kit-accurate-calcium-alkalinity) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-18*
