put few drops of tap water on white cardboard.
directly put 1 drop of co2 indicator into tap water. observe what color it is.
Yes bro Weijie, did that way, but i'm using wife's cup instead of white cardpboard...its yellow-green with water from aquarium tank, green-blue with tap water, looks the tester chemical is doing fine, my concern is, why the indicator doesn't change in color after i put it into mop pail filled with tap water
Weijie, do u have Amazonia 9L powder type in stock? PM me the price
