I am in the process of building a new pool, about 12,000 gallon gunite/shotcrete with in floor cleaning system. Since this my first pool I am looking for any advice on what would be an acceptable system. We are working with prices from three builders, two of the builders are set against an SWG system. They will install them if I really want them but one builder says he hasn't installed any in 2 years and the other says the majority of their service complaints are dealing with SWG's. Of course the third builder has an SWG and says he has no issue with his or their SWG installations.
Since this pool will be constructed at our second home, the pool will be used at various times with various bather loads. I am looking for the system that will provide the least amount of maintenance since I would like to have a pool maintenace company only stop by once a week( is that a reasonable maintenance schedule?).
I understand water balance is critical with any system but I am wondering why the two builders are so against the SWG systems. Is the hard water in Phoenix the reason the builders are recommending against the SWG? Is there a way to bring down the hard water? The two builders recommendations in place of the SWG was to use chlorine pucks, does anyone have opinions on pucks?
Thanks for any assistance you may provide.
