Why pool shock matters for Krum 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.
Krum is characterized predominantly by well water systems, with mineral content often exceeding 800-1200 ppm TDS depending on well location and depth. Groundwater contains elevated calcium (300+ ppm), iron (0.5-2.0 ppm), and sometimes sulfates creating persistent scaling and staining challenges. Water hardness requires aggressive treatment with sequestrants, chelating agents, and possibly saturation index management to prevent surface damage. The water chemistry is among the most challenging in our service area, requiring experienced technicians who understand well water treatment protocols deeply. Many Krum property owners have struggled with service providers unfamiliar with well water, making our expertise a significant differentiator.
