4dkh solution is used in co2 drop checkers and, when combined with co2 reagent solution, provides a simple but effective method of monitoring the co2 levels of your nature aquarium. As the level of co2 in the aquarium changes, so to does the PH of the 4dkh and reagent solution which then changes colour. Blue signifies that the level of co2 is too low, lime green is ideal and yellow being is too much.
