How we manage and maintain the water in a pond will have a direct effect on the health and growth of our pond fish.

There a over a dozen different test kits available, each testing for a specific water parameter.

When maintaining a koi pond we need to understand, analyse, interpret and respond to a handful of chemical data, sometimes on a daily basis.

Time and time again we read and are told that water quality is of paramount importance when keeping fish, especially koi.
