Hoping you guys can help this first-time pool owner troubleshoot my very cloudy in-ground vinyl 30,000 gallon kidney-shaped pool. Located in Long Island, NY. Filter is a Sta-Rite System3 cartridge filter. No green is present, just milky cloudy blue.
We had it opened by our pool guy a week ago today. It was very green upon opening. He instructed 15 gallons liquid bleach and 5 pounds shock. The green was gone within 24 hours. Have been running the filter 24/7 to try and clear cloudiness, but really no change. I've hosed down the filter cartridges 4 times in the past week. Our Sta-Rite System 3 filter has been operating at the max PSI of 30 nearly the entire week. The only time it drops to around 20 PSI is the 2-3 hours following a cartridge cleaning (when the system has been off for 30-45 min). Return flow to the pool seems fine regardless of PSI. Although, the Polaris vacuum which was inspected and set up by our pool guy only moves immediately following a filter cleaning, then comes to a dead halt.
Had the water tested at our pool store midweek and was instructed to put in 10 pounds shock followed by a clarifier. No change to the cloudiness.
FC - 1.4
CC or TC -1.4
pH - 7.0
TA - 120
CH - 150
CYA - Cyanuric Acid (stabilizer/conditioner) - 0
With regards to the stabilizer, pool guy instructed 4 pounds put in after the green went away, which we did. Guess it didn't stay around.
Thanks very much,
