Why pool shock matters for Lewisville pools
Shocking isn't about "more chlorine" — it's about rapidly oxidizing organics (sweat, oils, urine, algae) that normal chlorine can't keep up with. Using the wrong shock makes problems worse: cal-hypo raises calcium hardness (bad in DFW hard-water areas), dichlor raises cyanuric (bad if you're already high). Picking the right shock for your current water is the difference between a clear pool and a chemical bill that keeps climbing.
Lewisville is served by municipal water from the City of Lewisville system, sourcing from Lewisville Lake and the DFW water supply network. Water quality is good with moderate mineral content (300-400 ppm TDS). The proximity to Lewisville Lake means seasonal algae pressure can be higher, particularly in summer and early fall. Municipal water is generally favorable for pool maintenance with consistent chemistry year-round.
