I use RO water for my aquarium and these readings help me maintain my parameters as desired. Very good product! Review: Pricey but works as expected! - Works as expected. The results have to be counted in drops of the solution added to the water and wait for color change. The chart comparison provided is in degrees, instead of drops counted. There might be a bit of confusion at first, but its not that difficult to understand. Very costly but i guess that's what you need to pay to know the water quality with such accuracy and also there aren't many options either. ## Features - Liquid test for freshwater - Helps detect stress on fish caused by rAPId ph shifts, the result of low kh levels - Contains clear instructions and glass tube(s) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003SNCHMA | | Best Sellers Rank | #5,205 in Pet Supplies ( See Top 100 in Pet Supplies ) #23 in Test Kits | | Generic Name | API GENERAL/CARBONATE HARDNESS KIT | | Importer | VM Classic Pets Pvt Ltd | | Item Dimensions LxWxH | 7 x 4.1 x 13 Centimeters | | Item Weight | 70.8 g | | Item model number | 58 | | Manufacturer | API Fish Care, Aquarium Pharmaceuticals | | Net Quantity | 1 Count | | Packer | APi Fish Care | | Product Dimensions | 6.99 x 4.13 x 13.02 cm; 70.87 g | ## Images ![Aquarium Pharmaceuticals, API, MARS Fishcare Gh and Kh Test Kit - Image 1](https://m.media-amazon.com/images/I/518PHJWONXL.jpg) ![Aquarium Pharmaceuticals, API, MARS Fishcare Gh and Kh Test Kit - Image 2](https://m.media-amazon.com/images/I/91q9ER-WJFL.jpg) ![Aquarium Pharmaceuticals, API, MARS Fishcare Gh and Kh Test Kit - Image 3](https://m.media-amazon.com/images/I/51hXtDFPf0L.jpg) ![Aquarium Pharmaceuticals, API, MARS Fishcare Gh and Kh Test Kit - Image 4](https://m.media-amazon.com/images/I/71GkdCyCuBL.jpg) ![Aquarium Pharmaceuticals, API, MARS Fishcare Gh and Kh Test Kit - Image 5](https://m.media-amazon.com/images/I/81T3-ZFwqBL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very good product *by A***N on 30 March 2026* Very accurate and extremely easy to use. I use RO water for my aquarium and these readings help me maintain my parameters as desired. Very good product! ### ⭐⭐⭐⭐⭐ Pricey but works as expected! *by P***R on 30 November 2017* Works as expected. The results have to be counted in drops of the solution added to the water and wait for color change. The chart comparison provided is in degrees, instead of drops counted. There might be a bit of confusion at first, but its not that difficult to understand. Very costly but i guess that's what you need to pay to know the water quality with such accuracy and also there aren't many options either. ### ⭐⭐⭐⭐ Plastic box and glass test tubes please *by A***A on 10 March 2026* It is a must have kit for aquarists. One star less for no plastic box to keep the kit safe and plastic test tubes, not glass test tube. A little pricey. ## Frequently Bought Together - API GH & KH TEST KIT Freshwater Aquarium Water Test Kit, 2.5 oz. - API FRESHWATER MASTER TEST KIT 800-Test Freshwater Aquarium Water Master Test Kit, White, Single, Multi-colored - SaltyShrimp Shrimp Mineral GH/KH+ 100g --- ## 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.de/products/71687880-aquarium-pharmaceuticals-api-mars-fishcare-gh-and-kh-test-kit](https://www.desertcart.de/products/71687880-aquarium-pharmaceuticals-api-mars-fishcare-gh-and-kh-test-kit) --- *Product available on Desertcart Germany* *Store origin: DE* *Last updated: 2026-07-23*
