Take your chlorine level up to 15 and try and hold it there for a few days. Test at least twice (and more than that is even better) times per day and each time, add enough bleach to get back to 15. When you get to where you don't lose more than 1ppm of chlorine from sundown to sunup then you can let it drift back down and keep it between 3-6 all the time.

Does your cl drop below 3 any? What are you using as your source of chlorine?

You are right to run the pump 24/7 while you are trying to clear the pool.

You say this has been going on for weeks. Can you please tell us what all you have been doing -- how many times per day testing, how high taking the cl when you add it, what all you have put in the pool meaning ingredients, not "shock."

We'll help you get it cleared up.
