Why muriatic acid matters for Lewisville pools

DFW water comes out of the tap at pH 8+ in most cities and pushes higher as your pool heats up in summer. Without regular acid dosing, you get cloudy water, scale on the tile, reduced chlorine efficacy, and skin/eye irritation. Muriatic acid (31.45% hydrochloric) is the fastest, most economical way to correct pH and alkalinity — but it's dangerous to ship, handle, and dose incorrectly. We deliver it packaged for heat, with the pro handling advice.

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.

Muriatic Acid questions from Lewisville customers

Why does pH keep climbing in my Lewisville pool?
Lewisville is on municipal water (typically Upper Trinity Water District or DCUD), which is relatively clean — TDS under 500 ppm — but summer irrigation demand and Texas heat still push chemistry around. Combined with Texas heat and any waterfall, spa spillover, or fountain, that fill water drives pH steadily upward all summer. On municipal water in Lewisville, weekly pH adjustment during June-September is the norm. The fix is to drop total alkalinity first (target 80-100 ppm); once TA is in range, pH stops climbing as fast.
Can you deliver muriatic acid to Lewisville?
Yes — UPS, FedEx, and USPS all refuse to ship muriatic acid (it's a DOT hazmat), but we run our own trucks through Lewisville (75029, 75056, 75057, 75067) and the rest of Denton County every weekday. Cutoff is 2 PM for same-day. Arrives in heat-protected packaging with a one-page dosing guide specific to your pool size.
How much muriatic acid does a typical Lewisville pool need weekly?
Varies by pool size and how aggressive your alkalinity is. Most Lewisville pools are plaster or pebble — finishes that show staining fast if chemistry slips. For a ~20,000 gallon pool in Lewisville, most owners use 16-24 oz per week during summer — a 1-gallon jug lasts about a month. Bring us a water test and we'll print an exact weekly schedule.
Is dry acid safer to use than muriatic in Lewisville?
Safer to handle, yes — sodium bisulfate is a granular powder, not a liquid, so no splash risk. But it's 2-3× more expensive per dose and it raises total dissolved solids over time. For a Lewisville homeowner who dislikes handling liquid muriatic, dry acid is a fair tradeoff. For weekly maintenance on a larger pool, muriatic pencils out better — we deliver it to you in a closed container so there's no trip to the pool store.
How do I add muriatic acid safely?
Always add slowly in the deep end with the pump running; never mix with chlorine; dilute large doses (over 1 pint) in a bucket of pool water before adding; wear gloves and eye protection. Wait 4+ hours before re-testing pH.
Why can't UPS ship muriatic acid?
All common carriers classify muriatic acid as DOT Class 8 corrosive hazmat — prohibited on normal ground or air. Only pool-supply delivery services licensed for hazmat transport can carry it, which is why our local delivery is often the only practical option for DFW pool owners.
