6‑in‑1 test – test strips, pack of 10

This pack of ten test strips lets keepers check six key water parameters in a single step, without separate reagents. It suits anyone who maintains an aquarium or pond and needs a quick routine check of pH, hardness and nitrogen compounds, as well as chlorine in tap water used for top-ups.

Why it matters

• One strip covers six parameters: pH, general hardness (GH), carbonate hardness (KH), nitrite, nitrate and chlorine.
• The procedure takes one step: dip the strip and move it for one to two seconds, shake off the excess water, then read the result after 60 seconds.
• Results are matched against a colour chart printed on the packaging, which shows whether each value falls within the safe range.
• The Tetra Aquatics app can read the strip with a smartphone, giving a digital reading instead of a visual comparison.

What it works with

The strips are designed for testing water in aquariums and ponds, and the chart and app are set up for these two uses. The leaflet included with the product gives guidance on corrective actions for values outside the safe range. Because the strips cover both hardness and nitrogen compounds, they are a practical companion to regular water changes and monitoring of tank or pond chemistry.
