Our 5-in-1 pool water test strips integrate five vital water quality indicators in one strip, covering free chlorine, total chlorine, pH, total alkalinity and total hardness to fully monitor swimming pool, spa and hot tub water conditions. Each bottle holds 50 test strips with a detailed color chart printed on the moisture-proof bottle cap for instant comparison.

Just dip the strip into water for 2 seconds and wait 15 seconds to get clear readings. Made of premium PET substrate, the test pads deliver distinct color changes with stable accuracy for daily routine inspection. Tight-sealed packaging protects strips from moisture and sunlight to extend shelf life up to 12 months.

Balanced water chemistry prevents algae growth, equipment scaling and skin irritation. Lightweight and portable, no complicated tools or calibration required. It is an affordable daily maintenance supply for DIY pool owners, spa operators and aquarium shops.
