Key Features: 15 mL bottle size – sufficient for multiple uses or frequent checks. Pre-mixed solution calibrated for 4 dKH carbonate hardness, giving accurate CO₂ level indication. Simple colour-change indicator: Blue = too low CO₂ concentration Green = optimal CO₂ levels Yellow = CO₂ concentration too high Ideal for all planted aquariums using a drop-checker monitoring system.
