Intex 3-Way Test Strips; Pool Maintenance And Chemical Definitions - Intex Krystal Clean Poolwater 8221 Owner's Manual

INTEX ® 3-Way Test Strips (packed with the Saltwater System/Filter Pump)
3-Way Test Strips can test the "Free Chlorine", "pH", and "Total Alkalinity" levels at the same time.
Directions and Use:
1. Dip entire strip into water and remove immediately.
2. Hold strip level for 15 seconds (do not shake excess water from strip).
3. Compare free chlorine, pH and total alkalinity strip pad to the color chart on packaging label. Adjust
pool water as necessary. Proper technique is important for water testing. Be sure to read and follow
the written strip instructions.

Is the chlorine residual present in pool water.
Is formed by the reaction of free chlorine with ammonia wastes.
Result if too high - Sharp chlorinous odor, eye irritation.
A value that indicates how acidic or basic a solution is.
Result if too low - Corroded metals, eye & skin irritation, destruction of total
alkalinity.
Result if too high - Scale formation, cloudy water, shorter filter runs, eye &
skin irritation, poor chlorine efficiency.
Indicates the degree of the water's resistance to change in pH. It determines the
speed and ease of pH change, so always adjust total alkalinity before adjusting
the pH level.
Result if too low - Corroded metals, eye & skin irritation. Low alkalinity will
cause the pH to be unstable. Any chemical added to the
water will have an affect on pH.
Result if too high - Scale formation, cloudy water, eye & skin irritation, poor
chlorine efficiency.
Refers to the amount of calcium and magnesium dissolved in the water.
Result if too high - Scale will form and will cause the water to become cloud.
Stabilizers extend the life of chlorine in swimming pools.
