And . . . that is why we NEVER trust pool store (or pool guy) results! Getting the CYA wrong by 400% is not 'close'!

OK. 5K gallon pool (15' x 3.8' water depth); PF=24. 1 gallon of PLAIN 8.25% bleach adds about 17 ppm of chlorine to your pool. (24*0.7 lbs /gal = ~17)

1. Start dosing each EVENING with 1 full gallon of plain bleach.
2. The following evening, test with OTO. If the result is clear to light yellow, add 1 more gallon. If DARK yellow, 1/2 gallon. If ORANGE, skip that dose.
3. Continue dosing in this manner for 2 days AFTER there's no trace of slipperiness or algae remaining.
4. Starting the 2nd night, BRUSH the pool completely every 2 days.
5. When you reach your final bleach dose (per #3 above), test 1 hour after dosing using the FAS DPD test. Test for BOTH FC and CC. Test AGAIN the following AM, before full sun hits the pool. Report those results here.
