I am going to attempt to give as much detail in a short post:
New plaster pool last Summer, 19,000 gal, SWG, cartridge filter; I check water as well as a service once a week. HAVE A COVERSTAR FULL AUTO COVER. Stays closed when not swimming. Went out of town and returned to cloudy water with greenish hue.
Tested water and then had Leslie's verify before I called the service frustrated. Water results:
FAC 0, TAC 4. Salt 3300, ok. CH 250, TA 120, pH 7.8. CYA? because the water is so cloudy to begin with but with a full cover it was generally 100 before issues.
I added 2 lbs Fresh N' Clear, waited 1 hour then brushed the entire pool and then shocked with 4 gal. Liquid shock. Did all this on Sunday and called pool service Monday. He told me "oh yah it looked cloudy July 2 so we added 1 gal shock and haven't been back yet." The problems with that response are obvious so I would like to focus on where I stand now. Pool service also tells me he changed the filter cartridges while I was away over the 4th.
Two days later the water is no longer green but still very cloudy and hasn't improved after another shock plus the service adding a Phos Free enzyme of some sort. Now he has added "drop out floc" and asked me to shut off everything(pump, polaris etc) and he is coming in the morning to vacuum. He tells me he checked the filters and internal manifold and both are fine.
MY QUESTION IS WHY AFTER REPEATED SHOCKING IS THE WATER STILL CLOUDY?
WHAT DO I NEED TO DO TO GET IT SAFE FOR MY KIDS ONCE THE WATER CLEARS?
ARE THE MEASURES THE SERVICE IS USING OFF BASE OR WITHIN REASON?
