Colombo KH Test Kits will help you ensure the correct Carbonate Hardness (KH) is maintained in your pond. For clear pond water and healthy fish and plants you need to monitor your KH and pH levels. KH is a measurement for the total amount of dissolved carbonates in the pond water. When the KH is too low the pH can fluctuate which is very harmful for the aquatic life.
If the value is at least 5 KH is the pH-value remains stable. A KH value of 8 is optimal.
Colombo KH Aquarium Test Kit contains 40 tests.
