Have 18 x 36 inground vinyl lined pool approx 27000 gallons . Have been doing this for 25 years and am really puzzled at this situation. Open pool 2 weeks ago, as usual vacuum most of algae and dirt to waste. Let pump run continiously 24/7. Added 12 gals Clorox directly to skimmer. This usually clears pool in about 2 days. Checked
readings. Have FC of 1.5, TC of over 10, PH 7. TA 80, CYA 30. Now after 2 weeks pool is cloudy and will not clear. Last night I
have added another 5 gallons of Clorox and this morning the FC reading very low around 1. and also the TC reading is down
to 1. and also notice a PH going to about 6.8. I just bought the Clorox from store so I would not think it is bad. I
have used 2 different test kits using new reagents. Unless the bleach is bad I can't understand why the FC reading will not get higher. Thanks.
