Benefits
✅ Lets you visually track pH shifts caused by CO₂ in real time✅ Helps you maintain stable CO₂ levels for healthier plant growth✅ Reduces the need for frequent manual test kits✅ Simple to install and monitor✅ Blends unobtrusively in your aquascape
How It WorksThe glass chamber is filled with an indicator solution that changes colour based on the pH of your tank water — typically shifting from yellow to green to blue as pH increases or decreases. This gives you a quick visual cue of changing CO₂ and pH levels.
Instructions for Use
Fill the small bulb with the provided indicator solution as instructed.
Invert the glass pH checker carefully so no solution spills.
Attach it inside the aquarium using the suction cup, away from direct diffuser output.
Monitor the color of the indicator to estimate pH changes:
Yellow = lower pH / higher CO₂
Green = moderate pH
Blue = higher pH / lower CO₂
Refill or replace the indicator solution as needed.
