PRO CO₂/pH Test

This kit is for aquarium keepers who need to track CO2 levels and want to avoid running pH tests every time they check CO2. The test is placed directly in the aquarium, and the result is read by comparing the colour change against the included scale.

Why it matters

• One test, two readings: the colour scale gives both the pH value and the CO2 level in the water.
• No repeated pH testing: the reading tells you the current CO2 level directly, so separate pH measurements are not needed for that purpose.
• Unobtrusive placement: at 3 x 4 cm, the test is described as practically invisible in the aquarium.
• Long usable life: one kit allows measurements for about 6 to 10 months.

What it works with

The kit is intended for freshwater aquariums where CO2 levels are monitored alongside pH, which is the setup implied by its placement in the underwater aquatics category. Because it is a colour-based test, it is used in the tank itself and checked against the supplied scale rather than connected to any electronic controller.
