Ok then...
So it is kinda what I figured. I just find it hard to understand how everyone (with their busy lives) still remembers to add dichlor to their spa every day or two.
If it ain't broke, don't fix it but this system leaves very little room for error IMO. Once the spa is without chlorine for any length of time, you've opened the door for cloudy, foamy water not to mention bacteria.
I bet a lot of you would find a chlorine floater far less work. It's not difficult to maintain a 1-3ppm reading with regular use of a floater. I do agree that the addition of ozone will help prevent the water from going "south" on you as quickly but I know with my lifestyle and my wife’s lack of interest in the spa chemicals, that adding dichlor with the frequency noted here, would never work for us.
Thanks for your input everyone,
Steve
