## 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.
