Free & Combined Chlorine

(Multiplier: x0.2 ppm)
Process:
  1. Rinse and fill the tube to the 25mL mark.
  2. Add 2 dippers of R-0870 powder. Swirl to mix (sample will turn pink).
  3. Add R-0871 dropwise, swirling between drops, until sample turns completely clear. (Record Free Chlorine drops)
  4. Add 5 drops of R-0003. Swirl to mix. If it stays clear, CC is 0.
  5. If it turns pink again, add R-0871 dropwise until clear. (Record Combined Chlorine drops)
FC: 0.0 ppm | CC: 0.0 ppm | TC: 0.0 ppm

pH Level

Process:
  1. Rinse and fill the large comparator tube to the 44mL mark.
  2. Add 5 drops of R-0004.
  3. Cap the tube and invert to mix.
  4. Hold against the white block below and match the color.
Hold your comparator tube directly against this block.

Total Alkalinity (TA)

Process:
  1. Rinse and fill the tube to the 25mL mark.
  2. Add 2 drops of R-0007 (to neutralize chlorine). Swirl to mix.
  3. Add 5 drops of R-0008. Swirl to mix (sample will turn green).
  4. Add R-0009 dropwise, swirling after each drop, until color changes from green to RED.
  5. Note: If a drop does not change the color further, do not count that final drop.
Total Alkalinity: 0 ppm

Calcium Hardness (CH)

Process:
  1. Rinse and fill the tube to the 25mL mark.
  2. Add 20 drops of R-0010. Swirl to mix.
  3. Add 5 drops of R-0011L. Swirl to mix (sample will turn red).
  4. Add R-0012 dropwise, swirling after each drop, until color changes from red to crisp BLUE.
Calcium Hardness: 0 ppm

Cyanuric Acid (CYA)

Process:
  1. Fill the CYA mixing bottle to the 7mL line with pool water.
  2. Add R-0013 reagent to the 14mL line.
  3. Cap and mix for 30 seconds. Wait 1 minute if water is very cold.
  4. Stand outdoors with the sun at your back. Pour mixture into the view tube until the black dot on the bottom completely disappears.
  5. Read the value on the side of the tube.
