Re: Downsides of SWGs - fact or fiction?
Yes, you can set it up to control PH with the sensor and run the chlorine in simple percentage mode. In the Installer menu look for the Select System entry and then pick pH Control. That will restart the unit in PH automation mode. I think you can also get the same effect in Total Control mode by disabling the ORP sensor on the Maintenance menu, but I haven't tried that recently.
It is very common for SWG pools to have an acid demand, but it doesn't need to be that way. The recommendations given out by most pool stores and web sites are far from ideal for a SWG, and that is what is creating the acid demand. By lowering your TA level down to around 60, adding borates, and raising the CYA level, you can dramatically lower the frequency of acid additions.
