I feel like my pool is never going to clear up!!! I started the SLAM process May 15th. Tested my ph...it was at 7.2. My CYA was very low in the beginning but I've since got it up to 50. I've added liquid chlorine to slam level according to my CYA level. So for the last 3 weeks I've been keeping my Chlorine at 20 sweeping everyday sometimes twice a day. Testing multiple times a day to keep the chlorine at the slam level. I've been vacuuming pool and have removed all solid material that I know of. Pump has been running non stop for a month and I've back washed as needed. I live in the south so I've gotten a lot of rain during all this but the last week or so it hasn't rained that much. I feel like I'm doing everything right but my pool is just staying cloudy. What am I doing wrong?
