I've notice a small amount of algae starting to grow and I need to shock. According to the Pool Calculator I need to bring my chlorine level to 18 and hold it there. My test kit (Taylor K-2005 ) will only read to 5 ppm. The testing vial holds 9 ml of water. So my question is, how many ml of pool water should I be using to perform my tests? For some reason I just can't seem to figure this out.
I seem to come up with an answer of approx 32 ml. Is this correct?
