    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. The Anti-Wickling-Design avoids water leaking out due to capillary effects when you fill your tank to the top.

    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!

    Supplied with one suction cup and 15 ml Indicator Solution.


    • Highest quality laboratory-grade borosilicate glass and artistically hand-blown
    • Supplied with 15ml Indicator Solution (4°dKH / 30 ppm CO2). No mixing nor preparation required
    • Perfect for aquariums 1-55 gallons
    • Can be hung on the rim of rimless aquariums (glass thickness less than 10 mm)
    • Solid white background behind bulb provides easy and accurate reading
    • Anti-Wickling-Design - Avoids water leaking out due to capillary effects

    Am 30L Nano Cube mit 5mm Glasstärke macht der Checker einen tollen Eindruck. Er ist leicht zu befüllen und eindeutig abzulesen. (mehr lesen)

    Sieht super aus, top Verarbeitung! Allein die Verpackung ist schon auf IPhone-Niveau:) Schön klein und dennoch super gut ablesbar, auch durch den weißen Hintergrund. (mehr lesen)

    Für ein 5mm dickes Aquariumglas ist er doch etwas weit - der Bogen. Aber er sieht sehr schick aus und erfüllt seinen Zweck.
