With the ownership of a new pool comes the responsibility of maintaining proper water chemistry. Maintaining proper water chemistry is essential in preserving the aesthetic beauty of the finish, as well as attaining the expected longevity of the finish. Please adhere to the proper Maintenance Guidelines found in the PTI Protection Plan. After 30 days, the pool water must be maintained per the National Plasterer’s Council for recommended ranges for pH, carbonate alkalinity, hardness, cyanuric acid/stabilizer and total dissolved solids; at all times. Salt water pools (SWCG’s) and PebbleFina Galaxy finishes should follow PTI’s “Start-up and Maintenance Procedures” instructions.
