Clear Colour Indication
Allow approximately 2 hours for the solution to stabilise before checking the colour:

• Blue: CO₂ level is too low
• Green or light green: CO₂ level is within the recommended range
• Yellow: CO₂ level is too high

Ideal for Planted Aquariums
Helps aquarium keepers monitor CO₂ levels and make appropriate adjustments to support healthy plant growth.

How to Use

1. Add the supplied reagent solution to the bulb of the glass drop checker.
2. Turn the drop checker upright carefully, keeping the solution inside.
3. Attach it to the aquarium glass below the waterline using the suction cup.
4. Wait approximately 2 hours for an accurate colour reading.

Important Notes

• Install the drop checker away from the CO₂ diffuser for a more representative reading.
• Do not allow aquarium water to mix directly with the reagent solution.
• Avoid making sudden or large adjustments to the CO₂ supply.
• Monitor fish behaviour and provide sufficient surface movement and oxygenation.
• Glassware is fragile—handle with care.
