WEEKAQUA CO2 Hanging Drop Checker with Solution

Key Features

• Sleek Hang-On Design: Unlike traditional drop checkers that rely on unsightly suction cups, this unit arches smoothly over the rim of your aquarium. The indicator chamber hangs neatly on the outside, offering a cleaner interior look and preventing aquatic life or algae from obstructing your view.

• Real-Time, At-a-Glance Monitoring: Provides constant feedback on the pH fluctuations caused by dissolved CO2 gas. Simply check the color of your reagent solution to monitor your levels instantly:

  • 🔵 Blue: Co2 is too low—plants aren’t getting enough nutrients.

  • 🟢 Green: Optimum CO2 levels (approx. 30 ppm)—perfect for lush plant growth and livestock safety.

  • 🟡 Yellow: CO2 is too high—dangerous for fish, shrimp, and invertebrates.

• High-Clarity Glass Construction: Made from premium, polished glass that blends seamlessly with modern rimless aquariums, ensuring the indicator fluid colors are vibrant and easy to read from across the room.

• Universal Rimless Compatibility: Designed to sit securely on standard rimless aquarium glass thicknesses (fits up to 10mm glass profiles perfectly).

How to Use

1. Turn the drop checker upside down and add 1–2 ml of your preferred CO2 indicator reagent solution into the bulb.

2. Carefully tilt the checker to guide the fluid into the lower viewing chamber, making sure it doesn’t spill over into the intake pipe.

3. Hang the unit over the edge of your rimless aquarium glass.

4. Allow 1 to 2 hours for the gas exchange to stabilize across the ambient pocket of air before adjusting your CO2 flow.
