Initially, thank you for this forum. It has been great getting an education from experience in manner that is geared toward self help processes. My question is in the getting started process. I just drained my approx 8000 gal pebble tec pool. New readings are: FC .02, TC .1, Ca+ 322, CYA 0, TA 128, pH 7.8, Diss solids 1000, phosphates 20. Been told to add the CYA @ 13 fl oz every couple of hours up to a quarter gal, then shock. Your advice?
