My parents in SC have been having algae problems and after 1 week of Chlorox shocking, all the algae is dead, water still cloudy but clearing via sand filter But the chemistry is so out of wack, they went to the local pool store for water analysis and he suggested the following add. Please let me know what you think as I am concerned over pH. They have a 28000 gal vinyl pool
FC 9, TC 9
add 25lbs baking soda
add 4 lb of CYA granules
5 lbs of turbo shock (bag says it's calcium hypo)
1qt algecide after adding shock
no filter backflushes for 48 hrs.
My calcs says he is adding the wrong stuff for pH, and I did not think he needed to shock pool based on the FC and TC. I also would not have added algecide until after the shock wears off and FC less than 10ppm
