I have fought for 2 years with our fiberglass pool to control stains, clouds and chlorine levels. I requested to have a SWG installed this year from my pool installer. He suggested and installed a BioGuard Mineral Springs system. Having no knowledge about this system, I was under the impression that my system would require a yearly 200-400 lbs of salt dumped in. Now I'm being told about "Beginnings" and "Renewal" weekly maintenance. WTH? I wanted to get away from weekly chem. Any suggestions and a big thanks from a SWG newbie.
