The key to successful fish keeping is excellent water quality. The NT Labs Pond Water Mini tests three water parameters: pH, Nitrite and Ammonia.
A full instruction leaflet is included in the pack which talks you through each parameter, what it should be, and what you should do if the readings are incorrect. This test kit reports concentration in terms of nitrogen (NH3-N) or (NO2-N) to be compatible with reported safe concentrations as they apply to fish.
