chevdog, I'm sorry, did I forget to mention that I'm sometimes psychic (or is that psycho?). Anyway, far be it from me to queer a sale for the guy but if you store water for a reasonably extensive period and then drain the tank (using the water for irrigation or ??) then refill again and superchlorinate, there is no reason to use automatic equipment, just a bleach bottle and measuring cup. I don't see any advantage to anyone (except the salesman) for a continuous throughput system vice a batch system except for a minor savings in your labor for a BIG increase in cost. OF course, for you, perhaps $ is not a consideration. [img]/forums/images/icons/smile.gif[/img]
