That's a big pool. Trying to handle it with 1 gallon jugs of 6% bleach will be a pain: 1 gallon would add only 1 ppm of chlorine!
  • Do you have any chemicals on hand? If so, EXACTLY what are they?
  • Is the pool covered? If it is, leave it covered, till you have chemicals AND a plan ready to go.
  • Do you have access to commercial liquid bleach OR 100lb containers of granular calcium hypochlorite?
  • What is the make / model of your filter & pump?

If your pool is NOT covered, and you have access to a Walmart and Lowes / Home Depot, I'd recommend adding 15 gallons of bleach in EACH evening. Add 2 gallons of muriatic acid (link to guide in my signature!) daily, but at least 30 minutes from when you add the bleach. Once we have more info, you can work out an alternative.

If possible re-test chlorine 1 hour after you add the bleach for the first time. If you had higher CYA last fall, you may now have ammonia in your pool. Dealing with that on a 52,000 gallon pool will take more than bottles of bleach, unless you want to go to multiple Walmarts and buy out each one's stock of plain bleach!
