CA Lic.#929667 = Weekly Pool Service: A trained technician will come each week and perform the following: Perform routine cleaning services such as a complete skimming of pool, brushing of tile, vacuuming of pool floor when needed, and the emptying of pump, skimmer, and leaf canister baskets. As well as the checking and balancing of Chlorine and Ph levels like most other pool services. But unlike most other pool services we also check total Alkalinity, Cyanuric acid, and salinity levels (for salt water chlorinating systems only) to ensure crystal clear and sanitary water. In addition to this, during the hot summer months (April - September) a highly effective algaecide is added each week for the prevention of forming algae. Also a weekly visual inspection of automatic pool vacuum, pool equipment and plumbing, leaving you with nothing to do but enjoy your "PRIMO" serviced pool.
