Hi guys, I've been remodeling my pool for the past few months. Now it's time for my equipment to get upgraded. I've upgraded my equipment to a Hayward Progrid DE Filter, pentair variable speed pump and two pentair whisperflo pumps for my water features. Now it's time for my old school timer to get upgraded. I'm not really worried about automatic valves but would like to turn my pool on and off from my Phone and also have the option for controlling solar heating later on. What products would you recommend for me? And what exactly do I need to purchase? Any help would be greatly appreciated. Also what do you guys think of used units? I've seen quite a few used aqualink systems for sale on eBay.
