Just thinking aloud really thought i would throw it out there see what people think .My pool is about 15 months old now and all is well happy with the trouble free method havent drianed down ,no green water etc .So now my pool gets a lot more use than i originally expected when i bought the pump/filter etc mainly due to the fact that we sort of opened it to the local kids so they could enjoy it ( we live out in the sticks in Thailand).i have a 1.5 hp Emaux pump that works fine with a Emaux 45g p/hr swg backed up with Liquid chlorine .If i run the swg 24/7 i get some pretty bad electric bills so was wondering if i bought say a 1/2 hp pump plumbed it next to the 1 1/2 pump with some no return valves on the outlets wpuld this be a viable idea to run say the main pump 8-10 hours a day then switch to the smaller pump (on timers) to run the rest of the 14-16 hours which would save a fair bit of money in the long run but produce a lot more chlorine .It is a cheaper option than replacing my pump with a variable speed one they start at about $900 US any thoughts ?
