Cal Aqua Labs Double Co2 checker
Cal Aqua Labs “Double Check” series is the only all-glass dual-compartment CO2 checker that allows the user to accurately compare the CO2 level in your aquarium side-by-side against a standard reference. The top chamber holds the CO2 indicator solution, whereas the bottom chamber carries a CO2 reference solution. The reference solution colour corresponds to 30 ppm of CO2 – a level that is widely accepted for good plant growth in most aquariums.
No more guessing on the shades of green. No more looking back-and-forth at colour sheets to compare. You know the precise CO2 level simply by comparing the colours in the two compartments side-by-side. Don’t guess, be sure! It’s as simple as that.
