Aquapro CO2 Drop Checker Hanging

• Correct Reading
• Easy to Use
• No Need to insert into tank

We are proud to present this beautiful over-the-rim drop checker so you can monitor your CO2 levels in style without having to deal with all the inconveniences of an in-tank CO2 monitor. The super low profile design looks great with any rimless tank, and is the best possible choice for smaller NANO aquarium where space is limited. Since the drop checker and indicator solution are held outside your tank, it will never fall in and the indicator solution will never mix with tank water giving your the most accurate readings forever!

• Never gets dirty, grungy or covered with algae. No need for cleaning!
• Thick, hand blown, high quality glass is beautiful and durable
• Will never fall off into your tank or get lost
• Accurate readings without the possibility of contamination with tank water
• Designed to compliment beautiful rimless aquariums where it becomes virtually invisible
• Perfect for Nano Tanks where space is at a premium as it takes up almost no space inside the aquarium
• Always visible at a glance – will never be covered with plants, dirty glass, algae, hard water stains or anything else inside an aquarium
• No suction cups to deal with

This beautiful accessory is designed for rimless tanks. This will fit most small rimmed tanks (10 gallon or smaller) and may be fitted after filing down some of the interior flange.
