I have been shocking the pool since Tuesday at noon, keeping FC levels 24 or greater using 6% great value bleach.
We have never had CC's until the past 2 days at 0.5 (due to storms both nights??). Passed the overnight drop test 2 nights in a row (last night went from 24 to 23.5 with a heavy storm), but there is no visible difference in the water. The shallow end looks clear, but in the deep end you have to squint to see the drain. At the beginning of the season I could see the drain from my upstairs bedroom window. There has been zero difference in the appearance of the water after 5 days of shocking. I have been brushing daily as recommended and keeping filter running 24/7 and SWG on "super chlor" except when doing overnight drop test the past 2 nights. when I backwash after vacuuming the water coming out looks normal, not dirty. In the mornings there is a small amount of debris but in the past I have definitely seen more. I would have expected more if I was "killing off" anything. what do I do next? I'm sick of buying bleach.....It is about 95-100+ degrees here every day for the past 3 weeks. Heavy storms every 4-6 days. I have missed out on a full week of swimming. This is no longer enjoyable.
CYA 20---This was a sudden drop from Tuesday's 40. 2 1/2 wks ago we added 4 lbs of stabilizer when it was at 40 and the CYA did not go up. Now it's suddenly 20????
