With a 15 ml volume capable of testing up to approximately 390°dKH, it provides reliable, easy-to-read results that help maintain stable pH levels critical for aquatic health. Highly rated by over 1,200 users, this kit is an essential tool for proactive aquarium management and pairs well with sera’s range of water conditioners. ## Description For approx. 390°dKH. In case of too low KH values we recommend sera KH/pH-plus (in freshwater) or sera pond bio balance (in ponds), in case of too high values we recommend filtering through sera super peat (in freshwater aquariums). Review: Worth it! - This titration test is easy, accurate and worth it. You can easily see the color change when it happens and have confidence in the results, unlike test strips. KH or alkalinity is very important for fresh and salt water aquariums. If it’s not in the range that promotes pH stability, then the ph will shift too fast and cause harm/death to your fish and invertebrates. If you have a hard time reading test strips for KH, try this! Review: I Like it - This test work it. I tested it with RO/DI water, so I knew the exact KH. ## Features - In the case of too low KH values we recommend Sera KH/pH-plus (in freshwater) or sera pond bio balance (in ponds) - In the case of too high values we recommend filtering through Sera super peat (in freshwater aquariums) - Makes it easy to monitor the carbonate hardness in fresh and salt water - 15 Milliliter / 0.5 Ounce Test Kit ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.6 out of 5 stars 1,288 Reviews | ## Images ![kH-Test 15 ml, 0.5 fl.oz.
