Green Aqua CO2 reagent 10 ml.

All drop checkers need to use 4dkh bromothymol blue solution. This solution is the most accurate on the market and once placed in your drop checker provides accurate results. In a planted aquarium the desired CO2 level for optimum plant growth is 30ppm. When your aquarium has this amount of CO2 in it, your drop checker will turn green – this is why it’s so important. So why shouldn’t you use tank water and the orange reagent that most drop checkers come with?


Tank water contains a variety of acids and alkalines some created by fish and shrimp, others added by hobbyists in the form of fertilisers for their plants. Therefore by using tank water in your reagent you’re adding a solution that is already changing and this is no good if you want accurate results – you need to start with a stable base level and go from there. This is where the 4dkH bromothymol blue solution comes in handy.
