Aqua Chek

AquaChek makes the test strips we recommend for every Arctic Spas water system. One one-second dip reads the numbers that matter: Yellow covers chlorine and salt-system spas (free chlorine, pH, total alkalinity and stabilizer), Red covers bromine tubs, the White salt strip verifies sodium chloride for Onzen and Spa Boy systems, Sodium Bromide strips serve bromine-based generators, and the 1-minute Phosphate test finds the hidden reason sanitizer disappears too fast.

Strips beat guesswork and they beat drifting electronics — when your salt system's display and a fresh strip disagree, believe the strip. Keep the bottle sealed and dry; humidity is what kills test pads. Free Ontario shipping over $169, or grab a bottle at any of our three showrooms.
