I shocked my pool a 2 weeks ago and got rid of green algae, added 6 bags of salt to get back up to @3200 and kept my SWG set at 60%. Chlorine production has been good, but water remains a bit cloudy. My filter cartridge was worn down, so I replaced it with a new cartridge 2 days ago. Water is still a bit cloudy. Below are my updated test results from yesterday:
Free Chlorine = 5.9 ppm
Total Chlorine = 6.2
Combined Chlorine = 0.3
pH = 8.0
Hardness = 48
Alkalinity (w/ stabilizer correction) = 59
Cyanuric Acid = 23
Copper = 0
Iron = 0
Total Dissolved Solids = Not run
Pool info: 21,000 gallon Fiberglass / Pentair SWG / Waterway ProClean 200 Cartridge Filter / 2-speed Hayward Pump (0.5/2.0 HP)
Since the chlorine level appears high, I turned off my SWG yesterday. I realize most of the other chemicals need balancing as well... my question is in what order should I balance these first? And which is most likely causing the slightly cloudy water?
Normally, I would lower pH first, but if I let the chlorine level come back down a bit.. will that lower the pH on its own?
