INITIAL FILL & BALANCING FOR OPTIMUM WATER CHEMISTRY

In accordance with the National Plasterers Council, Inc. (“NPC”) standards, it is recommended that the following pool and spa water chemistry conditions be maintained on an ongoing basis for the longevity of your pool and spa finish. These values are important to prevent corrosion, deterioration, discoloration, scaling or other problems. For more information refer to your local agency having jurisdiction or NPC.


Follow recommended fill and balancing procedures to ensure a successful start-up. Fill pool completely and without interruption with clean, potable water. The use of a filter during fill is strongly recommended. The initial fill water is the most important water that the pool will receive and must be tested, recorded and adjusted according to the following parameters by an experienced pool professional. For the first thirty days (30) the pH and alkalinity must be monitored and adjusted (if applicable) every three (3) to five (5) days. All other chemicals monitored and adjusted (if applicable) every seven (7) to ten (10) days. The pool water must be tested regularly and documented monthly by a reputable company using a computerized system. Monitoring the pool water regularly will not only affect the new finish but will keep the pool finish looking new. Improper water chemistry will void any limited residential/commercial warranty. It is recommended that a quality sequestering agent be used in the initial start-up in accordance with the manufacturer’s instructions and then a recommended maintenance dosage per the sequestering agent’s manufacturer instructions.


FIRST DAY:

Add sequestering agent upon initial fill per manufacturer’s instructions.

Adjust pH to 7.2 – 7.6 and total alkalinity to 80 -120 PPM.


SECOND DAY:

Record pH, total alkalinity, calcium hardness, and temperature levels. Adjust pH to 7.4 – 7.6 and total alkalinity to 80-120 PPM. Dissolve all chemicals completely in water before adding to the pool, and allow sufficient time for each chemical to be fully dispersed before adding other chemicals. DO NOT ADD CHLORINE. Brush the entire surface twice daily for the first three (3) days.


THIRD DAY:

Repeat steps from Second Day. Adjust chemistry to the following levels:


  • Free Chlorine: 1.0 – 3.0 PPM
  • pH: 7.4 -7.6
  • Total Alkalinity: 80 -120 PPM
  • Calcium Hardness: 200 – 400 PPM
  • Stabilizer: 30 – 60 PPM

Adjust the pump timer to normal operating hours. Do not install automatic pool cleaners for 28 days. Do not vacuum the pool with a wheeled vacuum for 14 days. Brush the pool walls and floor daily for the first two (2) weeks.


DAILY WATER CHEMISTRY AFTER 28 DAYS

Maintain the water chemistry using the Langelier Saturation Index (LSI) maintained between 0.0 and +0.3.
