I recently installed a Hayward SWG.
It recommends CYA level of 30-50.
I see that the Pool School recommends a much higher CYA of 70-80.
I have used a five gallon drum of acid in 6 weeks which is almost a pint a day.
I have now gone with TFP advice and ..
Upped the CYA.
Got TA in recommended range.
Will increase PH from 7.2/3 to 7.6 tomorrow I hope!.
Can anyone give me an idea of how much acid I should be using?
