FC consumption

[Rangerman]

CYA 70 (I know its too high)
Ph 7.5
TA 70
FC 20 (of SLAM 29)
Brought to 29 last night according to the calculator.
This morning's reading was 20.
Pool is full of algae (dark green)
Shouldn't there have been more than 9 points of FC consumed overnight?

Not necessarily. Keep your FC at SLAM level, brush, brush, brush.

Ranger,

Not necessarily, and with that CYA level you're gonna need a LOT of bleach. Remember you have to stay at or above SLAM level the whole time. Is there a reason you can't get the CYA down, like water restrictions? Are you running the pump 24/7?

Long story on the CYA. Assumed wrong there was no residual from last season. I added the amount to bring to 40. Subsequent test showed 100+. Confession, I went off the reservation and used Tri-Chlor pucks last year. I am paying for it now. Have been replacing water and trying to work with Mother Nature's heavy rainfall too.
Yes, 24/7 on the pump.
