Seachem Drop Checker

The drop checker is a glass pH monitor that comes with pH sensitive indicator solution. When submerged in water, this indicator solution changes colour according to changes in the pH of the aquarium as a result of CO₂ gas. The pH checker makes monitoring CO₂ concentrations and pH level in planted aquaria easy.

Yellow colour indicates too much CO2, green colour - optimal amount of CO2 and blue colour - insufficient amount of CO2
