As I plan the installation of a heat pump, it may also be time to reconsider the addition of a SWG. The six-year-old IG plaster pool holds 17k gallons and with an automatic cover it is always covered. Despite the mild climate on California’s Central Coast, the solar panels keep the temperature at 85-90 degrees for the five to six month swimming season.

The extreme amounts hydrogen sulfide in our well water is challenging to treat; however the treatment does not change the hardness of 900 ppm or 60grains, nor does it alter the Total Dissolved Solids at 2,000 ppm.

Hayward’s inline feeder doesn’t work, and most of the chlorination has been way of liquid or Leslies’ granular, and pucks in a floatie. On a weekly basis I’m using about 2 gallons of liquid or 2 pounds of granular, and 3 pucks in the floatie. I don’t recall the chemistry from last summer, however the CYA was off the charts. The guy at Leslies is familiar with my situation, and believed that the SWG would make matters worse with the high TDS, and hence the current chlorination regime.

But now that I’ll be doing some work, I’m open to reconsidering a SWG. Is the TDS really an issue? If not, what brand and size of SWG is best?
