I have a Biogaurd Mineral Springs , and I am being informed that I can use Mortans Pool Salt instead of Biogaurd New beginnings, Based on my current water testing at my local pool store, they inform me I need 14 bags (414lbs) of new beginnings for my summer start up, I have been informed by other people that I can use Mortans Pool salt? and after that I can continue to use the weekly bioguard treatment or just add Mortans pool sale as long as I keep my numbers right. Is this correct? This is a GREAT savings if this is correct and it will not damadge my system. Any and all HELP will be appreciated. This is my first post. THANKS
