Thanks Marie ......... for the very helpful response.

I did just use one (1) quart of poly 60 to open the pool just last week. As yu mentioned, maybe that is what is causing the suds. How long does it take to go away??
Been keeping the clorine high around 10-12ppm for the opening week, but will drop to around 2 next week.

Numbers as follows:

25k IG vinyl
Sand filter
CC 0
FC hig now (but will drop next week)
TA 120 - 130
pH 7.2 - 7.4
