Aquavascular CO2 Drop Check Indicator

Aquavascular CO₂ Drop Check Indicator – Real-Time CO₂ Monitoring for Planted Aquariums

Aquavascular CO₂ Drop Check Indicator provides a simple, accurate and continuous method of monitoring CO₂ levels in freshwater planted tanks. When placed inside a drop checker, the indicator reacts to the CO₂ concentration in the surrounding water by shifting colour. This allows aquarists to quickly understand whether their aquarium is receiving too much, too little or just the right amount of CO₂.

Maintaining proper CO₂ levels is essential for strong plant growth, algae control and overall aquarium stability. This indicator ensures that hobbyists can easily fine-tune their CO₂ injection system for optimal performance.

How to Use the Aquavascular CO₂ Drop Check Indicator

1. Fill the drop checker with the CO₂ Indicator Solution according to the device’s fill line.
2. Position the drop checker inside the aquarium away from filter outlets.
3. Allow 1–2 hours for the initial colour to stabilize.
4. Monitor the colour throughout the day:
   • Blue → Increase CO₂
   • Green → Keep CO₂ steady
   • Yellow → Decrease CO₂
5. Refill indicator solution weekly or when colour response slows.

Care & Maintenance Tips

• Clean the drop checker regularly to maintain clear visibility.
• Replace indicator fluid weekly for accurate readings.
• Avoid placing the checker near CO₂ diffusers or strong flow.
• Monitor fish behavior when adjusting CO₂ levels.
• Use consistent lighting and CO₂ schedules for reliable readings.
