Aquarium CO2 Drop Checker Solution (15ml) is a pre-made 4dKH solution that reacts to pH changes, this simplifies CO2 monitoring. To use, fill your drop checker 2/3 full with the solution (approx 15 drops), then install it inside the aquarium. The ideal CO2 level for planted aquariums is indicated by a light green colour. Replace the solution monthly for best accuracy. What do the colours mean?
