Penguin Pool Service is owner-operated and services swimming pools and spas in the North County Coastal areas of San Diego (Carmel Valley, Del Mar, La Jolla, Rancho Santa Fe, Solana Beach and Torrey Hills). We have years of experience managing pools with saltwater chlorine generators (salt pools). We also can help you to save energy with the latest variable speed pumps. Many pool service companies use diatomaceous earth in your pool filter because it's cheap. The truth is that Fiber Clear premium filter media works much better and keeps your pool water looking clearer. We only use Fiber Clear.
