This 3-in-1 pool water test strip bottle contains 50 strips for daily swimming pool and spa maintenance, testing free chlorine, pH and total alkalinity all at once to track core water balance. The measuring ranges match standard pool demands: 0–10ppm chlorine, 6.8–8.4 pH and 0–240ppm total alkalinity, also supporting bromine testing for hot tubs.

Simply dip the strip into water for 2 seconds and wait 15 seconds, then match colors against the printed chart on the moisture-proof bottle lid. Made of premium PET material, the pads create bright, distinguishable color changes for reliable visual readings.

Tight-sealed plastic bottle protects strips from humidity and sunlight to extend shelf life. No extra tools or calibration required, lightweight for outdoor on-site testing. Cost-effective and easy to use for DIY pool owners, spa operators and small aquaculture shops to keep water clean, balanced and comfortable.
