I installed a SmarterSpa SWG on my 400 G. hot tub. The Smarter Spa lets you control the max free chorine by adjusting how long it runs AND the minimum free chlorine by adjusting the sensor for when it turns on. What max and min free chlorine would you shoot for as I adjust it?
My tub is most often used by 1 person for 15-30 minutes about 7-10 times per week. It is used by two people for 15-30 minutes one or two times a week. Occasionally it's used by more people. I have used liquid chlorine so I would be willing to supplement occasionally with liquid chlorine and/or add MPS occasionally.
Also, what CYA would you recommend for my hot tub? I use 50 PPM borate. I know for pools the CYA is higher. In the TFP Pool School I learned, "CYA to between 70 and 80. The biggest mistake that many Saltwater Chlorine Generator owners make is NOT having enough CYA in the water! This can create a lot of problems like high acid demand, algae outbreaks, cloudy water, or early cell failure."
