Just trying to find out if anyone has tried to use the Intex units in an inground pool. I called Intex and got a generic response. I can't see why it would not work (we have a small inground pool (7500 gal)). The generator itself is 2 pieces of Titanium hooked up to a DC power supply. I guess I can't see why I should pay $400-700 when I can generate the chlorine just as well for less.
