We took the plunge and converted to a SWG a month or so ago. My CYA had been fairly low (it always go down during the winter months, maybe lots of rain or something?) but I just got some stabilizer and I've gotten it up to 60. I am still in the process of raising and will shoot for 80 given the long, hot Houston summers. I use the pool math app, and it tells me that in order to raise my chlorine I need to run the pump for a certain number of hours. I have a variable speed pump. Does it matter at what speed I run the pump?
