Hello to all and thank you in advance for your help. Ok, so my wife has been talked into buying the Perma Salt system. I just completed installing a new liner, and the pss this past week. Going on day three and the pool looks great. But when i took a sample of water in for checks, I was then bombarded with more items i needed to purchase to get the balance swim safe. My wife was shocked when i called her to say i had to buy other items such as calcium plus, total alkalinity plus stabilizer & conditioner. We bought the Activate and Klairate with the system, thus my qusition is is the later really nessary? Again thank you for your help?
