I've been having an interesting time managing my pool chemistry this season. I live in Arizona and we're regularly experiencing 100+ degree days. My family is pretty upset that the pool is either super-chlorinated or green. I have a 14500 in ground pebble-tech pool with a salt water generator and an ever-present green line at the water line. The SWG doesn't seem to keep the FC at a reasonable level.

After some research and professional advice, I was told to add 10 - 12 gallons of liquid chlorine to zap the algae and kickstart the FC. After 2 days, the water looks great, but I went from 25ppm to 1ppm in ~60 hours.

Here are the readings with my PS234.
6/24 (A.M.)
FC 25
CC .5
TC 25.5
pH 2.8
Alk --
Cya 30

6/25 (P.M.)
FC 7
CC .5
TC 7.5
pH 7.4
Alk 110
Cya 20

6/26 (P.M.)
FC 1
CC 0
TC 1
pH 7.5
Alk 110
Cya 0

I turned off the SWG based on advice from this forum. What's going on here? Is it normal to lose that much FC in so little time and my CC to remain fairly constant. Also, what about the drastic drop in Cya? Any help would be appreciated.

Please help me gain back the title of super-dad... My kids are looking at me with pathetic faces waiting to take a swim.
