    • Complete Test Kits

    Complete Koi Pond Test kits are the most popular method of analysing pond water. They rely on a chemical reaction between a reagent and pond water, resulting in a colour change that can be compared against a colour chart.

    Complete Test Kits make it easy for you to be able to perfomr many tests, without having to keep track of where each individual test kit is.
