CHLORINE DPD-1 = 3.0
CYA = OFF THE CHARTS AT 120
To date I'm using chlorine sticks in the feeder in the pump room
20x40 pool appx 26000 gal. water
avg depth 4.25
PH was low (at 6.6) so I used PH up and raised it to 7.0, then later in the week added soda ash to bring it up to 7.4
In the last 45 days I have drained below tile lines twice and refilled (appx 1/4 drain).
Low amount of bather load, any suggestions on how to get the CYA down w/o having to use the water drain/refill?? Drought is horrible here, and I don't want to waste water!
