GLASS PH CHECKER
Glass pH Checker that comes with a pH sensitive indicator solution. When immersed in water, this indicator solution changes color based on the changes in pH of the aquarium due to CO2 gas. The pH Checker makes it easy to monitor CO2 concentrations and pH levels in planted aquariums.
Suction cup included
Fill the container with 20 drops of indicator solution. Slowly twist the side of the funnel downwards, avoiding spilling the solution. Insert the pH Checker into the aquarium with the side down, trapping air in the funnel. Attach the pH Checker to the aquarium at the furthest point from any diffusers.
The color of the solution will change from yellow to green to blue based on the pH of the water
A more yellow color indicates a lower pH / too much CO2. A more blue color indicates a higher pH / less CO2.
