Why pool shock matters for Argyle 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.
Argyle is characterized by well water systems serving individual properties throughout the community. This groundwater typically contains elevated hardness (600-900 ppm), high iron content (0.5-2.0 ppm), and excess calcium, creating persistent scaling and staining challenges. The water chemistry requires consistent treatment with sequestrants and chelating agents to prevent equipment corrosion and plaster/surface staining. Many older wells in the area have even higher mineral content, necessitating more aggressive chemical management. Our well water expertise has made Argyle families strong, loyal clients who appreciate our understanding of their unique water challenges.
