Since your ph is so low and aerating the ph up can take time, I'd recommend adding some Borax. You need to get the ph up ASAP. I'm not sure why your pool is so cloudy. With your readings, it doesn't appear that algae is the cause. Had your chlorine dropped too low recently? If so, perhaps you did have some algae starting but you zapped it with the high cl and the algae just hasn't all filtered out yet? Or, it could be from adding something to the water. Exactly what all have you added to the pool recently?
