With a low dKH reading PH was always in jeopardy of crashing. ### ⭐⭐⭐⭐⭐ It works *by M***. on April 4, 2025* I like the quality of the materials, the glass vial with stopper, and the dropper itself has a nice design. As to its accuracy, it matches my API test kits, and is no more difficult to use. ### ⭐⭐⭐⭐⭐ Worth it! *by A***A on September 3, 2023* 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! ## Frequently Bought Together - sera kH-Test 15 ml, 0.5 fl.oz. Aquarium Test Kits - sera pH-Test 15 ml, 0.5 fl.oz.
