I do add bleach on occasion, primarily after a big rain or large group swim. Even when I turn the SWG up full blast, it seems that it can, on these rare occasions, get behind the curve and have trouble keeping enough active CL in the water to handle the large loads. It only happened 2 or 3 times last year (heavy load/rain, next day pool is cloudy, FC is low) and I use 2 or 3 gallons of bleach to clear it up.

Overall, I'm really happy with it. The one occasion we had to call the support line, they were fabulous and talked my wife through resetting the system and getting it working again.
What are your pump run times with the SWG set at 25-50%? I have the same size pool and will be installed an Aquarite this month. In prior seasons, I have run my pump for 2 blocks of time, each 4 hours long. I will liklely start up on that same schedule with the Aquarite, but have a feeling that my run times will increase.

Thanks,
