PRODUCT LABEL CHEMICAL DOSAGE Amount of Chemical (from Appendix B-2 or product label) Actual Pool Volume in Gallons Desired Chemical Change Total 375,000 Litres ÷ 95,000 Litres (From appendix B-2 or product label) 1 Litre (from product label) X = 3.95 3.95 Litres (rounded to 4 litres) Product label chemical adjustment example. You have a 200,000 litre condominium pool. There was a pool party on Friday night and the usual weekend bather load. On Sunday morning you observe the pool water to be cloudy and test a free chlorine level below 1 mg/L. You decide to treat the pool with 8 mg/L of additional chlorine using calcium hypochlorite. The label states that 630 grams will raise the chlorine level 10 mg/L in 40,000 litres. How much cal-hypo should be added? PRODUCT LABEL CHEMICAL ADJUSTMENT Amount of Chemical (from Appendix B-2 or product label) Actual Pool Volume in Gallons Desired Chemical Change Total 200,000 Litres 8 mg/L ÷ 40,000 Litres (From appendix B-2 or product label) 10 ÷ mg/L (From appendix B-2 or product label) 630 grams (from product label) X X 0.8 = 5 2,520 grams Conversion: 2,520 ÷ 1,000 = 2.5 kilos No Product label chemical adjustment example. You have a 160,000 litre pool. The free available chlorine level is 1 mg/L. How much sodium hypochlorite is needed to raise the chlorine level to 3 mg/L?

NO PRODUCT LABEL CHEMICAL ADJUSTMENT Amount of Chemical (from Appendix B-2 or product label) Actual Pool Volume in Gallons Desired Chemical Change Total 160,000 Litres 2 mg/L ÷ 40,000 Litres (From appendix B-2 or product label) 1 ÷ mg/L (From appendix B-2 or product label) 330 mL (from product label) X X 2 = 4 2,640 mL Conversion: 2,640 mL ÷ 1,000 = 2.64 litres Key Points: Briefl y discuss free chlorine, total chlorine and combined chlorine. Include a discussion on how to reduce or prevent organic chloramines that includes the options of: Water replacement, breakpoint chlorination (BPC), ultraviolet (UV) Ozone, potassium monopersulfate and indoor air handling Activity: Work the students through breakpoint chlorination chemical adjustment. Use the following data: 208,000 litre pool with a FC = 1.5 mg/L, a TC of 2.3 mg/L and a pH of 7.4. Facility uses calcium hypochlorite. Emphasize that the desired changes is a result of CC x 10 minus existing free chlorine value. (see example on page 75 of the Pool & Spa Operator Handbook). Use the same Chemical Adjustment Worksheet to perform the breakpoint chlorination calculation. (There are several more sample calculations in the Pool Math Workbook that may also be used.) Key Points: Discuss the source of minerals in pool water and their effect on pool water when they are oxidized. Include: Source of minerals such as fi ll water, inadvertent additions of lawn and landscaping chemicals, algicides, and corrosion due to poor pool water chemistry Cause of green, red, brown or black water and methods of correction Key Points: Discuss other commonly used chemicals and their possible effect on pool water. These include: Algaecides – Used to eliminate algae from pool water. The most common algaecide compounds include quaternary algaecides, polymeric algaecides, and metallic (copper) algaecides. Stain removers – Chelating agents bond the metals into larger compounds that can be removed through fi ltration. Sequestering agents remove metals by dissolving them into solution. Water clarifiers are used to clear cloudy water. Emphasize that this is a temporary solution to a bigger problem, usually poor fi ltration. © 2014 <strong>National</strong> Swimming Pool Foundation® Page 63
