Pro Shrimp's comment: Liquid Test Kits are more accurate than the common test strips and enable you to do more tests per package. KH determines the carbonate hardness of your water, KH plays an important factor in regards to pH stability.

We stock refills as well!

  • Recommended level: for fresh water 4-8 °dKH. for saltwater: 7-10 °dKH.
  • Colour change from blue to yellow. The number of used drops = level of carbonate hardness.
  • For this reason this test does NOT require a colour scale.
  • The most important test in aquatics since the KH stabilizes the pH value.
