API Freshwater Master Test Kit: spot invisible water problems before they harm your fish

Most water problems are invisible to the eye. The API Freshwater Master Test Kit is a liquid reagent kit that measures the five water parameters most important to the health of freshwater fish: pH, high range pH, ammonia, nitrite and nitrate. With over 800 tests in the box, it is a cost effective way to keep on top of routine weekly testing.

Why Choose the API Freshwater Master Test Kit?

• Five key tests: pH, high range pH, ammonia, nitrite and nitrate, the parameters tied to fish health and the nitrogen cycle.
• Professional accuracy: liquid tests are more precise than strips, helping you catch water quality issues early.
• Over 800 tests: great value for regular weekly monitoring.
• Easy to read: computer calibrated, laminated colour card for clear results.
• Tells you what to do: follow the recommendations on the card if action is needed.
• Ideal for new tanks: track ammonia and nitrite while cycling a new aquarium, during maintenance or when troubleshooting.

What It Tests

• pH: measures how acidic or alkaline your aquarium water is.
• High Range pH: for tanks that need a higher pH.
• Ammonia: detects this toxic compound released by fish waste, uneaten food and decaying matter.
• Nitrite: shows this toxic nitrogen compound, which hinders fish respiration.
• Nitrate: indicates long term waste build up that can stress fish if levels get too high.

What's in the Box

• 7 bottles of liquid test solutions
• 4 glass test tubes with caps
• Test tube holding tray
• Computer calibrated, laminated colour card
• Step by step instruction booklet with guidance on interpreting results and correcting unsafe conditions

How to Use

Fill a test tube with 5ml of aquarium water, add the test drops, holding the bottle vertically, and compare the result to the colour card. Follow the instruction booklet for each individual test. Test weekly for best results, and rinse the test tubes with water straight after each test to prevent staining.
