iTrader Positive Rating: 100% | CO2 Checker Hello,
The instructions say to fill the top chamber half way with #4 standard and add 2 to 4 drops of pH indicator until a clear blue color appears.
I got a clear blue color after one drop and did not add anymore. Would this make a differance in the CO2 reading from blue to green? |
