Its accuracy, ease of use, and durability make it a standout choice for both beginners and experienced hobbyists. If you're serious about maintaining optimal water parameters in your aquarium, I highly recommend incorporating the Salifert Calcium Test Kit into your routine. It's a game-changer! Review: Excellent and easy to read - Excellent, as most Salifert test kits have been in my experience (I don't recall if I've tried their copper; for that I use Hanna's high range kit which works with saltwater). Accurate per multiple kit testing from a Reef2reef.com article I read where someone tested the various kits against a Triton standard, precise, and the end points are easy to determine so it feels very reliable and trustworthy (as opposed to Elos, which also works well with slightly less precision but the endpoint is harder to determine with my eyes). Fairly simple, with only 1 extra step from the Elos. I also only use Salifert for alkalinity and magnesium as well. ## Features - The calcium test kit provides for accurate calcium levels - The calcium test kit can perform up to 100 tests - The calcium tests is capable in resolving calcium contents - The Package Weight Of The Product Is 0.5 Pounds ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B001EIZT4Y | | ASIN | B001EIZT4Y | | Best Sellers Rank | #31,000 in Pet Supplies ( See Top 100 in Pet Supplies ) #43 in Aquarium Test Kits | | Brand Name | Salifert | | Customer Reviews | 4.6 4.6 out of 5 stars (656) | | Date First Available | August 19, 2008 | | Department | Fish & Aquatic Pets | | Included Components | Salifert Calcium (Ca) Test Kit - 50 Tests | | Is Discontinued By Manufacturer | No | | Item Type Name | Aquarium Water Testing Kit | | Item model number | 8714079130347 | | Manufacturer | Deepwater Aquatics Distribution | | Manufacturer | Deepwater Aquatics Distribution | | Model Number | 8714079130347 | | Part Number | 8714079130347 | | Product Dimensions | 5 x 5 x 4 inches; 3.53 ounces | | UPC | 714097130341 | | Unit Count | 1 Count | | Warranty Description | Please see manufacturer website for details | ## Product Details - **Brand:** Salifert - **Manufacturer:** Deepwater Aquatics Distribution - **UPC:** 714097130341 - **Unit Count:** 1 Count ## Images ![Calcium (Ca) Test Kit - 50 to 100 Tests - Image 1](https://m.media-amazon.com/images/I/61-OTr29N4L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ My go to test kit brand! *by M***N on December 4, 2023* The Salifert Calcium Test Kit to my aquarium maintenance toolkit, and the results have been nothing short of impressive.
