The API Liquid Master Test Kit – Freshwater is a highly accurate and reliable liquid reagent test kit designed to help you monitor the water quality in your freshwater aquarium. Regular testing of key water parameters is essential for maintaining a healthy environment for fish, plants and other aquatic life, and this kit gives you the tools you need to keep on top of it.

What It Tests:

• 📊 pH – measures acidity/alkalinity of aquarium water

• 📈 High Range pH – for tanks with higher pH needs

• 🧪 Ammonia – detects this toxic compound produced by fish waste and decomposing matter

• ⚠️ Nitrite – shows intermediate toxic nitrogen compounds

• 💧 Nitrate – indicates long‑term waste buildup that can stress fish if too high

What’s Included:

• 7 bottles of liquid reagent test solutions

• 4 glass test tubes with caps

• A holding tray and computer‑calibrated, laminated colour comparison chart

• Step‑by‑step instruction booklet with guidance on interpreting results and correcting unsafe conditions

Why It’s Great:

• 🐠 Professional accuracy: Liquid tests are more precise than strips, helping you catch water quality issues early.

• 🔍 Comprehensive panel: Covers the most critical parameters tied to fish health and the nitrogen cycle.

• 📆 Long‑lasting: Provides up to ~800 tests, making it a cost‑effective choice for routine weekly monitoring.

How It Helps:
