§01 Industrial-corridor air chemistry
Pasadena's air carries enough sulfur and particulate from refining that pool chemistry behaves differently here than 20 miles inland. We pre-balance for it instead of reacting to it — fewer green-tinted weeks, less chlorine demand.
§02 Strong sun & evaporation rates
Pasadena yards run hot and the prevailing wind speeds up evaporation. We dial in higher CYA and watch fill-water hardness so calcium scaling doesn't sneak up — a chronic issue here that most service companies miss until you see it on the tile.
§03 Aging mid-century construction
Plenty of Pasadena pools were built in the 60s and 70s with copper plumbing and concrete decks. We service them as-is, tell you when something is at end-of-life, and renovate them when you're ready.
