I got about a month with the 1st season with my pool. I seem to go through about 2-ish gallons of chlorine a week. At $7/gal I'll be using about $675 worth of chlorine a year. It'll probably be less during the off season since I won't have my pool at 88 degrees.
Main thing is right now, the kids are in there every other day and the weather is nice. I'm motivated to go clean the pool, test the water and add chemicals. When it starts to rain and cold out, it'll be a different story.
I really like the idea of SWG but also see there are other options as well.
If I can get a system under $1k I think it'll be worth it cause it'll pay for itself in 2 years. Any suggestions?
