Nyos Alkalinity Test Kit Nyos Alkalinity Test Kit is a high sensitivity seawater alkalinity test kit for measuring carbonate hardness in marine and reef aquariums. Stable alkalinity is critical for coral growth, pH stability, and predictable reef chemistry, making reliable KH testing one of the most important parts of regular aquarium maintenance. Alkalinity Testing for Marine and Reef Aquariums This Nyos REEFER kit uses a simple titration format with a precise colour change and direct KH reading on the syringe. It is well suited for routine reef testing, monitoring alkalinity consumption, checking dosing systems, and keeping carbonate hardness stable for corals and other reef livestock. Nyos Alkalinity Test Kit Features High sensitivity seawater alkalinity test kit for carbonate hardness testing. Designed for marine and reef aquarium use. Easy-to-use titration test with clear colour change. Allows KH to be read directly on the syringe. Calibrated German-made dropper supports uniform drops during repeat testing. Reagents are made in Germany under strict quality control. Designed for approximately 50 analyses at an average alkalinity of 10 dKH. Alkalinity Test Specifications Product type: Seawater alkalinity test kit Parameter tested: Alkalinity / carbonate hardness / KH Number of tests: Approx. 50 at an average alkalinity of 10 dKH / 3.5 meq/l Application: Marine and reef aquariums Test method: Manual titration Test kit series: Nyos REEFER Manufacturing: Made in Germany Reef Testing Notes Alkalinity should be tested regularly in reef aquariums, especially when using two-part dosing, calcium reactors, kalkwasser, or other alkalinity supplementation methods. Track results over time and adjust dosing gradually to avoid rapid KH swings. Nyos Alkalinity Test Kit Video Directions for Use Rinse the sample container several times with aquarium water, then add the required water sample using the included syringe. Add reagent CH-1 and swirl gently as directed, then add CH-2 drop by drop while swirling until the colour changes from blue to red-orange. Read the alkalinity value from the syringe according to the included instructions. Store reagents properly and keep bottles closed when not in use.
