CO₂/pH test – supplementary information

This JBL refill is intended for aquarists who already use the JBL CO2/pH test and need to restock it without buying a complete kit. It lets you keep monitoring carbon dioxide and pH in a planted or freshwater tank, which is useful when checking whether CO2 supplementation is balanced for your plants and fish.

Why it matters

• It is a replacement set for the JBL CO2/pH test, so the existing test kit can continue to be used once its reagents run out.
• The test is designed for quick determination of CO2 concentration in the aquarium water.
• Measuring CO2 alongside pH allows you to read the two values together, which helps interpret the water chemistry of the tank.
• The product is a small, lightweight consumable (0.05 kg), easy to store next to your other water-testing supplies.
