Couple questions... At one point it says to add 2 gallons bleach, then another after brushing. So I am adding 3 gallons of bleach nightly? Also your post says 3.5 ft, my pool is 48" or 4 ft (not sure that matters?), but want to make sure dosage is accurate. I continue this nightly, till the pool is clear and blue or how do I know when the algae is gone? Alot of what I have read says to make sure ph is correct, how will I know if not by testing? Thanks so much for your help!
