I'm using a swg and my cya is around 50-60. tested yesterday using the trouble free test kit. I was told by the manufacturer that its best to let the swg run at night and then burn off the built up chlorine during the day. I tested last night around 6pm and the chlorine level was around 1ppm. Is this too low? Do I need to aim for it to be higher than that? swg is running from like 10pm to 8am now. I've noticed algae starting to grow so I'm guessing I need to up the chlorinator time. should I raise the cya more? I am leary of going too high because then when there are problems, it takes lots and lots of chlorine to kill it.
Its also been very hot here the past week, around 95-100 for the past week in florida.
