My pool has been cloudy for 3 weeks. Ever since I opened it. I have a 5 year old AG 30 ft (20,0000 gal) pool with a 1.5 hp Hayward pump. I have a 250 lb 18 in. Sand filter. I have been using the BBB method for 2 years. This year I cannot get the cloudiness to go away. I have been trying to keep the chlorine level at 15 ppm for the last 4 days to kill algae. I have also completely changed the sand in my filter yesterday. Here are my numbers, thy have been running pretty consistent for the past week or 2.
As of this morning:
FC 10 (just added 7 ppm this morning to boost)
Calc hardness 70
