Overview
The CO₂ Drop Checker Kit includes a transparent drop-checker and ready-to-use 4 dKH indicator solution. Hang it inside your aquarium to monitor CO₂ via simple color cues—blue = low, green = optimal (~30 ppm), yellow = high—typically stabilizing within 2 hours due to CO₂-pH equilibrium.
Key Features
- Pre-mixed indicator solution: Supplied in a 15 ml dropper, calibrated for 4 dKH—no DIY mixing required .
- Clear glass/acrylic body: Durable, transparent housing for easy color reading and aesthetic appeal .
- Suction-cup mounting: Secure placement on tank glass or rim ensures consistent immersion and reliable readings .
- Accurate CO₂ estimation: Measures equilibrium at ~30 ppm CO₂—optimal balance for plant health and fish safety .

Why Use This Checker?
- Stress‑free CO₂ monitoring: Color-based feedback shows if CO₂ is too low, ideal, or over-dosed .
- Safer aquaria: Prevents COâ‚‚-related fish stress by detecting over-dosing early (yellow indicator).
- Convenient & reliable: No mixing, easy mounting, and long-lasting solution (replace monthly) .
Usage Tips
- Invert drop checker and add solution until bulb is ~â…” full .
- Attach suction cup ~15 cm below the surface; avoid direct bubbles .
- Allow 2 hours for color stabilization.
- Interpret colors: Blue = low CO₂, Green = optimal (~30 ppm), Yellow = excessive .
- Replace solution monthly to maintain accuracy .
