Hi everyone, I recently bought a drop checker but it doesnt come with 4dkh solution and making it with baking soda and water without the sensitive accurate scale sounds very hardcore. Anyone know an easier way to make this? And also. It doesnt come with a color card. Are all DC's read the same way?
It came with a bottle that says CO2 liquid tester. And says to add 5 drops and fill with aquarium water. Need feedback
