    Cal Aqua Labs' PEARL series is a 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 unique space-saving design places the reference chamber right inside the the indicator chamber. The inner chamber holds the CO2 reference solution, whereas the outer chamber carries a CO2 indicator solution. The reference solution color 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 color sheets to compare. You know the precise CO2 level simply by comparing the colors in the two compartments side-by-side. Simply adjust your CO2 level so that the color of the indicator solution matches that of the reference solution. Don't guess, be sure! It's as simple as that.

    Each set includes a PEARL CO2 checker, 15ml Reference solution, 15ml Indicator solution, one suction cup and two reference chamber plugs.


    • Highest quality laboratory-grade borosilicate glass and artistically hand-blown
    • Unique dual-compartment design. Inner compartment holds the Reference solution, while the outer compartment holds the Indicator solution
    • No solution preparation needed. Required solutions are premade and included
    • Simple to use, simple to read, higher accuracy than other single-compartment checkers
