Description
Cal Aqua Labs' PEARL 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.
The Pearl is hand-crafted using only the highest quality, laboratory-grade, borosilicate glass for maximum strength, durability, and visual clarity. Each piece is unique.

CAL AQUA LABS PEARL DROP CHECKER
Great product! We have to use a drop checker. Why not make it one that has the reference color built into the checker. A win, win situation.

Pearl Drop Checker
Very easy to correctly set CO2 levels having the reference media inside chamber

Very Nicely Made
A beautiful product, with simple instructions that allows for a quick install. This adds an easy way to my tank for checking CO2 levels. It’s been up and running for a day now, but it looks great. I do wish the instructions included information on how often you should refresh the solutions or if they never need to be changed.
