I'm betting that I'm spinning my wheels. I need help with this because it's just not registering for some reason. How long should my Chlorine stay above 15ppm? Until it's clear? I just keep dumping in bleach? Last night my FC measured at 10ppm. I poured in a gallon of bleach at 8pm. As of 5am this morning my Chlorine is up to 19ppm. How can I hold it there? Should I put in more bleach now? Should I test again at noon and if it's below 15 I just dump in some more bleach?

I'm sorry if I sound ignorant.. but I really want to get this right. I am wasting so much money and the pool is essentially useless until we clear it up.

By the way.. the water turned much darker green yesterday.
