Hello Everyone, I recently moved into a new home with a pool and spa. I drained the pool, had it cleaned and then installed the Hayward Aqua Plus controller with the Total Chemistry kit and Acid Feed system. I've never owned a pool and really don't understand all this chemistry stuff, but I was hoping to get a somewhat "maintenance free" system. Anyway are there any proven system settings for this set up as far as controlling PH and ORP levels? The other day I was finally able to use my spa after having to replace the heater and I noticed the PH shot up immediately. The acid feed system starting pumping acid and then when I was done with the spa and the water cooled back off the PH was too low and now I'm getting "check system" warnings on the controller. I live in Phoenix, AZ if that has any effect on the settings. Any help would be appreciated. Thanks!!!
