Drop Checker

Depending on the species of aquatic plants you keep, the growth conditions and the water hardness, the amount of CO₂ you will need to supply may vary greatly.

The Drop Checker is a monitoring device made of glass that shows you the amount of CO₂ that is dissolved in the water at all times. The pH reagent contained inside will change color if the amount of CO₂ changes. By comparison with a colour chart you can easily find out how much CO₂ you need to add to your aquarium.

1 bottle of pH reagent included (5 ml)
