How often per day are you dosing?
I think rechecking your CYA is prudent here.
Are you using fresh high quality bleach of at least 8.25%? No bargain bleach or bleach from Lowes/HomeDepot/Dollar Store......right??
Thanks for replying.
I've tested CYA 4 times or so with a consistent 30 to 35.
Using Great Value 8.25% from Wal-Mart, literally took bottles out of the boxes from the stocking clerk.
Drunk and gonna go backwash and dump another gallon in.

When a pool is algae laden.....chlorine will kill it. Honestly, that pool looks like it has never had any chlorine in it.
Are you vacuuming and brushing? are you keeping the FC continuously at SLAM value?
Chlorine is always the answer. Use it evenly but make sure it is in there ALL the time.
Are you running the pump 24/7?
Yup, brushed 3 times today. Vacuumed twice yesterday and the day before, but didn't today.
Pump has been running 24/7 since last Monday.
