The water was tested for phosphates a week ago and there wasn't any in the pool.
I tested this morning at 9am and the FC was .25 and the CC was .25, using the FAS-DPD kit. I can only hope that it's a sign I (we) are getting rid of the contaminant. But the FC is being used at a really high rate to get rid of the TCL, so maybe it was ammonia as chem-geek had said. I will not use calcium hypo as their suggestion as the pool is cloudy, I wil try the LC regimen you suggested starting Sunday morning , my day off !!
You want me to test every half hour ?? Is that sufficient time for the first 5 gallons to get around ?? And then I will top off as you suggested. At this point I am also contemplating removing half the water, which would still keep the liner in place and replacing with clean water, my only question is will this dilute the contaminant enough to then be able to kill it with a "normal" chlorine maintnenace program ?? Your help is really appreciated.
