I have little chlorine and was told by Anthony Sylvan pools to,empty my pool to,get rid of nitrates.My pool contractor told me to add about 10 gallons of household bleach tonight and super chlorinate with 10 lbs of granular chlorine.I don't want to raise my CYA too high and added 4 lbs of shock today is 10 gallons of bleach tonight too much for 27,500 gallons..I Do have mustard algae in some areas.
