Usage & Maintenance Instructions

To ensure accurate readings and maintain the integrity of the solution, please follow these simple steps:

1. Prepare the Checker: Thoroughly clean your CO2 drop checker. Crucial: Ensure the inside of the drop checker is completely dry before adding the new fluid.

2. Fill: Drop an appropriate amount of the indicator solution into the drop checker (typically until the glass bulb is about half full). Note: The initial color of the fluid will be blue.

3. Install: Carefully submerge the drop checker into your aquarium, ensuring an air bubble is trapped inside the chamber to separate the tank water from the indicator fluid.

4. Wait: Allow 1 to 2 hours for the solution to react with the gases in the aquarium and display an accurate color reading.

5. Routine Replacement: For the most accurate results, replace the solution inside the drop checker approximately once every 30 days.

6. Storage: Keep the bottle tightly sealed and store it airtight at room temperature, away from direct sunlight.
