JBL Combiset Complete Test Kit

The JBL Combiset Complete Test Kit is a professional-grade liquid testing solution that measures pH, KH, GH, NO2, NO3, NH4/NH3 (ammonia), and O2 (oxygen) in freshwater aquariums. All reagents are stored in a neat, compact case alongside test tubes, pipettes, and laminated color reference charts. JBL's formulations deliver high precision comparable to laboratory methods, making this kit a favorite among serious planted tank and discus enthusiasts. The oxygen test is a standout feature not commonly found in competitor kits, useful for CO2-injected tanks and high-stocking scenarios. Each parameter has its own dedicated reagent bottles and detailed instructions in multiple languages.
