Ensure the ideal CO2 levels in your aquarium with our CO2 drop checker solution. Accurately monitor and maintain optimal conditions for your aquatic plants and fish, promoting a vibrant and healthy underwater environment.
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?
As CO2 out-gasses into the drop checker, the indicator colour changes based on the aquarium's CO2 concentration: green means optimal levels, blue indicates low CO2, and yellow signals high CO2 levels.
