so this is the second year i had my pool. this year i opened it by shocking and flocking. the water was so clear but then a week later it was cloudy and white stuff building up on the bottom and sometimes it could be yellow to green. i then shocked and flocked again and it was good for about 6 days and then the same thing happened and two days after that it was really bad so i shocked and flocked again and also trying to figure out this slam method. i have about 11,000 gallons and when i checked my levels right before the last shock and flock i had 3 ppm cl, and 55 cya. the test kit says these ranges are fine but it didnt look fine. so yesterday after i vacuumed from the flock i then started slamming but not sure im doing it right. i added 2 gallons in the am then 2 b4 i left for work last night. today when i got home i did two more gallons. this seems overkill. am i doing this right?
