Just in case it wasn’t understood that chlorine needs to be added pretty much daily. Going back to your original question: depending on how large your pool is, adding 21oz of chlorine may or may not be enough for one days use. But chlorine is consumed every day so it needs to be maintained above the FC/CYA level every day.
