Above Ground 15K Gal
After a Hard Rain I had to let out about 2.5 inches of water. I checked the Chlorine level it was 1 ppm the PH was 7.0
I raised the PH to 7.5 and raised the chlorine to 8 ppm other levels were TA=130 CH=325 CYA=41
The Water got very cloudy with a tint of green. I vacuumed the brown/green from the bottom each day and backwashed sand filter. I also brush everything
After 3 days I raised the chlorine 18. still the same after a few days.
Now FC=18 CC=.5 PH=7.5 TA=300 CH=130 CYA=49 Same routine vaccum,brush, backwash.
a day later (now) same readings and same water. cloudy hard to see bottom.
It is accumulating brown/green dust like on the bottom so I vacuumed it again (Daily).
What is next step? SLAM?
