Green Leaf Drop Checker
Green Leaf Drop Checker allows you to accurately and continuously measure, at a glance, CO2 levels in your planted aquarium.
For the first time on the market, we are including a bottle of KH Standard / 4 dKH (lab certified analytical standard 4 dKH) that when combined with pH indicator (Bromothymol Blue), creates the necessary and appropriate solution to accurately measure CO2 levels. The KH standard / 4 dKH needs to be combined with 2 - 4 drops of pH indicator in your drop checker until a strong transparent blue color is achieved. Carbon Dioxide (CO2) levels are determined through a comparison of the vital drop checker solution with a pH color test card.
BLUE -> Low CO2 levels -> Increase rate of CO2
GREEN -> Proper CO2 levels -> No action required
YELLOW -> High CO2 levels -> Decrease rate of CO2
- KH Standard / 4 dKH solution included
