API Freshwater Master Test Kit
Fish need properly balanced levels of ammonia, pH, high range pH, nitrite and nitrate. The API FRESHWATER MASTER TEST KIT measures these six parameters with scientific accuracy and provides professional results. It comes with four glass test tubes, a holding tray, test tube rack and computer calibrated, laminated colour card. Just fill the test tubes, add the test drops and compare results to the colour card. Then follow the recommendations on the card if action is required.
- High Range & Low Range pH: Check if your aquarium pH is stable and suitable for your fish
- Ammonia (NH₃/NH₄⁺): Detect toxic ammonia spikes from waste and uneaten food
- Nitrite (NO₂⁻): Monitor nitrite levels during cycling and after maintenance
- Nitrate (NO₃⁻): Track long-term water quality and prevent issues from high nitrate
- Comprehensive Kit: Includes test tubes, color charts, and liquid reagents
