OK, here is the status at the end of the first 24 hours.

Last night - Added 3 1/3 bottles (174 fl.oz size) and watched the color change. I had to use my MS Excel to convery gallons to 174 fl.oz bottles.

This morning the water was still green and cloudy, and FAC was zero, backflushed and added 2 more bottles before work.

After work, all the cloudiness fell to the bottom, vacuumed some nasty stuff to waste and added a couple inches of water. Test results:

FAC was 1.5, TAC was > 5.0, pH was 7.8, Acid Demand - recommended adding 3 lbs pH decreaser, ALK was at 210 ppm. I question the pH, acid demand and ALK results with the TAC above 5.0.

Added 2 more bottles for tonight, a total of 10 gallons so far.

Should I adjust the pH?
