Cisco,
Does your salt cell clog with scale build up? I have the same issues with CH and PH rising quickly. I go through 2-5 gallons of acid per week just to keep the PH down around 7.2-7.5. The SWG cell clogs with scale every day. I have to remove and clean with a power washer. MY Ch is also 600+ and there are scale flakes that come out of the return lines into the pool. I have considered bypasing the SWG as it is more problem than normal maitenance. However, I just feel like I am missing something and should not give up on it. Any help is appreciated. Thanks
