Hi Sandy,

I'm running it just enough to keep it looking nice since it's in full view out the back patio doors. A couple of hours usually takes care of it, plus a little time with the net. I'm going to experiment with leaving it off as long as possible and see what happens. I haven't really measured the water temperature, so it's probably closer to yours since it's also uncovered and unheated.

I go to www.weather.com and look at the 24 hour forecast to see when the temperature is going to drop into the twenties, and if it's late at night I'll set the timers accordingly.

It has low CYA - probably around 20ppm by now, so I can run relatively low chlorine, usually around 2ppm. I use bleach and then a little muriatic acid to control pH.
