Single Carbonate Hardness Test Strip

Using a Carbonate Hardness Test prior to applying certain algaecides and herbicides in your pond is recommended. A Water Hardness greater than 50ppm helps fish that are sensitive to chemical treatments. Harder water assists your pond in controlling varying pH levels and will prevent heavy metal impurities from killing your fish. In addition, harder water usually breeds higher alkalinity levels that will absorb acidic pond content without changing pH, thus keeping your fish safe. These water hardness test strips are simple to use and will work in just a matter of minutes.
