Monopersulfate

Okay…I will finally admit it. I belong to the ILSWAC (I Love Spaghetti Westerns Addiction Club). I can’t get enough of badly written, badly acted, badly directed Westerns, usually made in Italy from the 1960s and 1970s. The “badder” the better. Anyway, here’s the good, the bad, and the ugly about a treatment product being used in the pool/spa industry that has gained tremendous popularity in the past 10-ish years: potassium peroxy-monopersulfate (KHSO5), aka monopersulfate or non-chlorine shock. Now, I’m going to be very picky here, monopersulfate is NOT a non-chlorine “shock” since shock infers killing something, and monopersulfate doesn’t kill. It should correctly be referred to as “non-chlorine OXIDIZER” because the product keeps organics from our bodies (and other sources) from developing into combined chlorine (chloramines) — the odorous, itchy, rash-producing form of chlorine that is not a good thing to have. In fact, the industry usually recommends combined chlorine be removed once it reaches >0.2 ppm. <a href="https://medium.com/@taylorpool/monopersulfate-the-good-the-bad-and-the-ugly-368187c5ce75">Website</a>
