Cal Aqua Labs Clip CO2 Checker (With Suction)

Available stock: 2

Most glass CO2 checkers on the market today can only be attached to either the left or the right side of the aquarium, and all the checkers on the market requires that the entire unit be completely submerged INSIDE the tank. This may by inconvenient especially for small tanks, where space is limited and the presence of the device can distract you from your aquascape.

Cal Aqua Labs' CLIP is the first CO2 checker that can be mounted on either the left, right, or the back side of the aquarium, allowing greater flexibility in the device's placement within the aquarium. It's low visual profile takes up very little space and minimizes distraction from your aquascape. For rimless aquariums and nano tanks, it can also be hung on the rim with most of the unit outside the tank. This provides unsurpassed clarity, greatly minimizes the amount of equipment inside the aquarium, and prevents debris buildup on the unit itself. Furthermore, the white background behind the bulb of the unit makes color readings easy and accurate. Never before has a CO2 checker been so versatile!
