Pool had algae, been slamming for 2 days now. At 9am the FC was 3.75 an CC was 0.5...added bleach back to shock level. At 6pm FC was 3.8 and CC was 0.15....pool is milky colored now instead of green...I keep raising chlorine to shock level until when? I have read the slamming your pool section. Just confused now.
