CO2 Indicator Solution – Drop Checker for Planted Tanks

Description

The CO2 Indicator Solution is a simple yet powerful tool for monitoring carbon dioxide levels in your planted freshwater aquarium. It works by hanging a small glass drop checker on the inside wall of your tank and filling it with this indicator solution.

• How it works: Add 15 drops of solution into the glass drop checker vial, then observe the color change over time.
• Green: CO2 is at an ideal, natural level — your plants are thriving.
• Yellow: CO2 is too high — reduce injection or increase surface agitation.
• Blue: CO2 is too low — your plants need more carbon dioxide for healthy growth.

The solution is replaced once per month, making it a cost-effective long-term monitoring solution for any CO2-injected planted tank.

Perfect for aquarium hobbyists running high-tech planted tanks or CO2 systems inand beyond. Understanding your CO2 levels is critical to preventing algae outbreaks and ensuring lush, healthy plant growth in local water conditions.
