You are not going to be able to test pH until your chlorine level drops. By the way, use the 10ml sample instead of the 25ml sample so your testing reagents will last longer. Keep the chlorine high while it is cloudy and run your pump 24/7 to let the filter do its job. And, have patience. It takes time to clear up a cloudy pool.

(Do you have this very same question posted elsewhere on the forum? i'm pretty sure I answered this exact question before. )
