I have opened the pool and the water looks great. However, I cannot get a FC above .5. Twice in the last couple of weeks I have added more than 12 cups of dichlor (each time) and have had little change in the FC level. Last night I added 9 large jugs of bleach (about 13 gals) and 15 minutes later the FC reading was unchanged at .5 to .8. I poured a qt of bleach into the swimout part of my pool (dead spot) that is perhaps 3 1/2 ft x 1 1/2 ft and perhaps a foot deep. I took a reading a minute or two later and the FC level was still unchanged. I'm using a Taylor K-2006 with the following latest results.
FC: .5 to .8
Ph: 7.0 (in process of attempting to raise)
CYA: 25-50 (Hard to measure.)
