Arctic Pure | Adjust Up

Arctic Pure Adjust Up raises the pH of your hot tub water. If your test strip reads below 7.2, this brings it back into the safe zone.

Why low pH is a problem: acidic water is corrosive — it eats at heater elements, pump seals and metal fittings, stings eyes and skin, and burns through sanitizer faster than balanced water. The ideal range is 7.2–7.6.

How to use it: with at least one pump running, add one capful — that raises the test strip about one colour change. The 2 kg container's larger cap holds roughly three small capfuls. Circulate, wait at least 30 minutes before using the spa, and retest before adding more.

Quick tips:

• If pH keeps sagging no matter how often you raise it, your total alkalinity is almost certainly low — fix that first with Perfect Balance
• Several small doses beat one big one; the goal is 7.2–7.6, not "as high as it goes"
