Hi all! I'm new here, but have done some lurking in the past. We had a fiberglass pool installed 5 years ago. Now we're sick of the chlorine, and thinking about changing to a SWG. I'm getting a bit overwhelmed, every place I've tried getting a quote from offers a different brand. My husband is a fairly handy person, is a SWG something we could potentially install ourselves, or a job best left to the pros? I'd love some brand recommendations, or brands to avoid. My pool is only 11,500 gallons.
