My pool is indoors and was cloudy/white 2 days ago. It's been beautiful for the last 3 months. I shocked w/recommended 12 to 16ppm FC w/6% for a cya of 35, ph 7.2. Water turned green and very cloudy. I kept chlorine level at 16ppm all day and night. Usually pool would clear up by now. Yesterday I upped the FC to the 24ppm for mustard algae per The Pool Calculator but overshot and at 30ppm and kept it there. Ph at 7.0 and aireating w/jets to bring that up. The water never turned white as I expected for dead algae. Expected to see clear water this morning but still green tint and fairly clear. Backwashed but very little came out. I added Super blue yesterday w/no results.
Test results from 10-31 w/TF-100 kit
15,000 gal
1 1/2 hp Pentair pump
Pentair Triton TR100 Sand Filter
Heat Siphon Heat Pump
fc-6.0
cc-0
tc-6.0
ph-7.4
ta-200 (high I know)
ch-300
cya- 35
water temp- 90
Any ideas? I'm suprised to see the green tint with such high fc. I've heard of chlorine lock but never experienced it. Pool owner for 30 yrs.
Thanks
