I'm getting ready to convert to a SWG. I almost went for the cell that connects to my plumbing but didn't want to run the pool pump just to create salt. I found that there is solar chlor (has buint in solar generator and can create chlorine around the clock and independent of my pool equipment. And then there's chlorease. Chlorease says it's for above ground pool but will service 18,000 gallons. I have a 17,000 gallon inground pool. My question is will the solar chlor really get enough power from the sun to generate chlorine for my pool? And for the chlorease (which runs via 110v GFI), i'm not worried about power, but will it work for inground pool? I'm assuming the only difference between inground and above ground water is the pool cost. Other than that, what's the difference? Please help.
