if you have ammonia then that will destroy the chlorine before the sun can get it. You just keep going at it and test every 15 mins, adding chlorine to get up to 10ppm after each test, until it holds FC. Repeat every 15 mins. Sun won’t eat that much in 15 mins.Ah that makes sense, thanks. If I have no CYA (because of that), wouldn't the sun destroy the chlorine added before it can do its job?
But you can’t add CYA until that bacteria is gone or it will just exasperate the problem.
