LUMEN GRANT PARK UPPER POOL

Observed pH of 8+. Chemical Values: pH 7.2 7.4-7.6 7.8 Alkalinity (buffering), 60 ppm 80-100 halogens compounds with high pH 180 ppm as CaC03 100-120 halogen compounds with low pH Calcium hardness, ppm, CaCo3 150 200-400 to balance water 1000 CPO will adjust pH level.

Observed Cyanuric acid at 100ppm. Stabilizer (if used) Cyanuric acid,ppm Ideal: 30-50 Maximum: 90 Comments: If stabilizer is: Too High: - May reduce chlorine efficacy Too Low: - Chlorine Residual rapidly destroyed by sunlight Note: Stabilizer is not needed in indoor or brominated pools and spas. CPO will adjust chemical levels.

Observed free chlorine at 24ppm. Free Chlorine level in pools using cyanuric acid or a stabilized chlorine product; Minimum 2.0 Ideal 2.0-5.0 Maximum 10.0 . CPO will adjust disinfectant levels.

Observed two flow meters, neither of which were operational. A flow meter measuring the rate of flow through the filter system with an appropriate range readable in gallons per minute (GPM) and accurate within ten percent actual flow shall be provided. The flow indicator shall be capable of measuring from one-half to at least one and one-half times the design flow rate. The gauge shall be located after the filtering equipment and in such location on the return line, so as to measure the total amount of water returning to the pool according to the manufacturer’s installation specifications. CPO will have flow meters repaired.
