I am contemplating switching from chlorine tabs and a 240 CYA number (I need to drain the entire 13,500 gal) to SWG. I currently have an Pentair Easy Touch 8 panel vintage 2006. What would be needed in the way of new equipment besides the SWG to make the change? Would it be best to stay with Pentair or go a different route? I did have an issue in operating an AmeriBrite color light that was recently installed with my older panel and I'm not sure if I would have a similar problem with the Intellichlor.
