I bought the Aquapure kit with sensor, plug and cell. I currently have an aqualink rs with the wireless phone option. I am confused what else I might need to buy to covert over to the SWG. I thought that's all I needed, then I keep seeing the purelink and aquapure power center. I thought I would be able to just connect the aquapure to my aqualink and control online through the web portal. I didnt think this would be this hard to figure out what I need. Any help would be appreciated. Thanks
