After 11 years of adding chlorine to my pool manually, I finally invested in a Stenner Econ T Pump and 15 gallon tank kit. Sure, I still have to lug jugs of chlorine occasionally, but I’m fine with that. After programming it and letting it run, I haven’t had to dose the pool manually, which I’ve normally had to do a couple of times a day In the warm months. Some will ask why I didn't go with a SWCG. Well, I also recently purchased a VSP, and I wasn’t willing to part with that much money so soon. And bonus, they make the product just on the other side of town.
