I actually gave up on my hot tub last year. It was just too much work to try to get it all right. Then the kids were on me to turn it back on. I started searching around for some better solution, when I ran across the Aero Spa ad. Like most people I was skeptical. I kept coming back to their website. I tried to find any downside to buying this contraption. Finally I gave in and bought one. It has been the best decision I've made concerning the hot tub. It's practically no maintenance. It just runs when it's supposed to and the water stays crystal clear. We finally enjoy the hot tub without any of the headaches. It's awesome.
