I assume the pool is filled?
  • 24' x 48 => 11,800 gallons (unless the bottom is dished). PF=10.1
  • 1 gallon of PLAIN (no flavor, no gel, no scent) 6% bleach will add (0.5 x 10.1) ppm of chlorine or ~5 ppm)
  • 1 gallon of 10% pool bleach will add (0.85 x 10.1) ppm of chlorine or ~ 9 ppm.
  • pH UP adjustment dose = 1 cup measure of borax
  • pH DOWN adjustment dose = 1/2 cup measure of muriatic acid

So . . .

If you can find this HTH 6-way at Walmart, get one. Otherwise order one from Amazon. (Yes, you'll want both).

While you are at Walmart, buy:
Test your pool in the EVENING. Make SURE the pump is OPERATING.
  1. If chlorine level is below 2 ppm, add 1 gallon of bleach or 1/2 gallon of pool bleach.
  2. If pH is below 7.2, scatter 1 cup measure of borax in the pool.
  3. If the pH is above 7.8, you will need some acid from Lowes or Home Depot. Read the "Using muriatic acid" article linked in my blue signature.
  4. Report results and actions in THIS thread.
  5. ALSO, list any chemicals that have ALREADY been added.

Good luck!
