Test Kit Chlorine/Ph/Alk/Acid Demand for Hot Tubs and Pools

PENTAIR RAINBOW TEST SOLUTIONS

DIRECTION:

Never let reagents remain in test vial. Clean and rinse after each test. Hold bottles vertically for proper drop size. Take water samples from a depth of 18” (away from return lines)

Chlorine residual

If reading is above 7.8, perform Acid Demand Test #3 using the same water sample. Test and adjust total alkalinity (if needed) before adjusting pH.

ACID DEMAND TEST (if Ph is above 7.8ppm)

·     Add solution #3 one drop at a time, counting drops, swirling between drops, until color matches 7.6 to Ph color standards.

Refer to Acid Demand Chart for proper amount of acid to be added to pool or spa.

TOTAL ALKALINITY

Fill large test vial to lower broken line.
