Hi Becca;

I looked at your pool chart info. I'm not sure who gave you the volume figure on your pool, but it's almost certainly incorrect. Assuming you have a deeper than average AG pool (54") with an actual water depth of 48", and a 28' diameter, your gallons are about 18,500, and your PF is 6.5.

What I need you to do, tomorrow evening I guess, is put 10 gallons of PLAIN 6% household bleach in your pool, and THEN test the chlorine level the next morning, before 9am, using an OTO (yellow drops) test. If the chlorine level is lower than DARK yellow, repeat the dose (10 gallons) that evening, and test again the following AM. Also BEFORE you add the bleach the first time, put in (4) boxes of 20 Mule Team borax (added slowly, via the skimmer, with the pump running).

So . . . when you go to Walmart or Kmart or wherever, you need to get:
+ (20) gallons of plains 6% bleach (check the %) or 27 96oz bottles
+ (4) boxes of 20 Mule Team borax
+ (1) OTO / phenol red kit. (Get the HTH 6-way drops kit, if your Walmart has it -- excellent value)
