I must be the royal dummy of all dummies--I read and read and still dont get it right. This past week I have put in over 40 gallons of bleach and still have green algae. The last 2 nights I have put in 15 gallons of ultra bleach and still green. Just tested using drop kit from walmarts.
Chlorine: had to dilute pool water with distilled water at ratio of 2/1 reading then showed 5/10
Ph: 7.5
TA: 170
CYA: 100
Pool size is about 32,000 gallons (not 50,000) like my pool guy told me.

Should I drain and start over???? Maybe drain 1/2 of water (getting a pump tomorrow) If drain 1/2 how much bleach to start ? Bought 40 gallons today--all walmart had!!!! What else should I add (if anything) if I do drain.

Any and All suggestions will be appreciated. Grandson wanted to have pool party this next week-end but afraid to plan. He is 10 and his baseball team won 2nd place this year so we wanted to have the celebration party here.

THANKS in advance
Karen
