Keep your aquarium’s water quality in check with API 5 in 1 Test Strips – 25 Strips, a fast, simple way to monitor the most important water parameters that affect fish health and tank balance. These convenient strips let you spot potential water issues before they stress or harm your aquatic life — no test tubes or reagents required.

What They Test:

• 📊 pH – Measures water acidity/alkalinity, essential for fish comfort and metabolic health.

• 🧪 Nitrite (NO₂) – Detects this toxic by‑product of the nitrogen cycle, which should stay very low.

• 📈 Nitrate (NO₃) – Indicates buildup of nitrogen waste — high levels can fuel algae growth.

• 💧 Carbonate Hardness (kH) – Shows buffering capacity that helps stabilise pH.

• ⚙️ General Hardness (gH) – Reflects dissolved mineral levels important for fish and plant wellbeing.

Why It’s Helpful:

• 🐠 Fast results: Just dip a strip in aquarium water, swirl briefly and compare colours to the included chart for readings in under a minute — perfect for regular checks.

• 💡 Comprehensive overview: One strip covers five key indicators, making routine monitoring easy and efficient.

• 🌊 Versatile: Suitable for both freshwater and saltwater aquariums.

• 📦 25 strips: Enough for frequent testing — ideal for weekly water quality checks or after water changes and maintenance.

How to Use:
Dip the strip into your aquarium water, remove it and compare the coloured pads to the chart provided with the strips. Testing regularly helps you spot drifting parameters early so you can take corrective action (like water changes or condition adjustments) before fish show signs of stress.

This 5‑in‑1 strip set is a convenient, cost‑effective tool for routine aquarium care and a quick check on water chemistry health.
