CYA "poll"

[JerryZ]

I keep mine at 80-90. I live in a HOT climate, my pool is full sun all day, and I have a large swimmer load on a daily basis. If I try to keep mine lower, there's no way to keep up with the chlorine demand without taking a chance on an algae bloom.

Ditto. I pull a bucket of pool water, set the Cl level with bleach, and test it during the day. On a moderately high UV day (8), I use 3.5ppm Cl at 80ppm CYA. I then calculate what cell output level is needed for various run times to generate that amount of Cl.

Running at 30 now. Save the pucks for going away. Try to keep below 50.
