What our high CYA pool correction covers in Lewisville

Diagnostic and water exchange service for pools with elevated cyanuric acid that suppresses active chlorine. Our technicians measure exact stabilizer levels with professional test kits, calculate safe partial drain volumes, and rebalance all baseline parameters after refill. Contact us to schedule an on-site evaluation.

  • ✓Stabilizer turbidity testing using Taylor Complete High Professional Test Kits (K-2005C series)
  • ✓Evaluation of active free chlorine to CYA ratios to determine required sanitizing levels
  • ✓Calculated partial drain-and-refill schedules based on total pool gallonage to reach 30–50 ppm CYA
  • ✓Submersible pump setup and monitored water evacuation to protect pool shell integrity
  • ✓Post-fill chemistry rebalancing: pH (7.2–7.6), total alkalinity (80–120 ppm), and calcium hardness (200–400 ppm)
  • ✓Feeder inspection and sanitation plan review to halt cumulative stabilizer accumulation

What we don't do (just so you know)

  • • Complete dry-draining of pool shells; water evacuation is performed in stages to protect structural integrity
  • • Chemical additive treatments for stabilizer removal, as physical water replacement is the only practical method to lower CYA
  • • Municipal water utility charges for pool refilling

Common high CYA pool correction symptoms we see in Lewisville

Algae returns within days despite regular shock treatments and tablet usageFree chlorine reads zero or near-zero on test strips despite continuous feeder operationCYA black dot vanishes near the top mark of the test tube (levels exceeding 100 ppm)Cloudy water that will not clear with standard filtration and routine chlorinationInadequate sanitizing speeds caused by a high CYA-to-free-chlorine ratio

If you're seeing any of these, call (469) 455-1054 — most are diagnosable in one visit.

About high CYA pool correction in Lewisville, TX

Lewisville is a major DFW suburb with over 115,000 residents spread across diverse neighborhoods ranging from established communities built in the 1980s to brand-new master-planned developments. The city sits along Lewisville Lake, one of DFW's most popular recreation areas, and benefits from excellent transportation access via I-35E and the DART rail system. The pool market in Lewisville is massive and varied — Castle Hills and other newer developments feature modern pools with premium equipment, while established neighborhoods along Valley Ridge and throughout central Lewisville contain thousands of older pools that benefit from regular professional maintenance and equipment updates. Lewisville's proximity to the lake means seasonal moisture and humidity can affect algae pressure, while the city's mature tree canopy creates leaf management challenges in many neighborhoods. The sheer number of pools in Lewisville combined with the diversity of ages and equipment types requires a service provider with deep technical knowledge and flexible service approaches. Our team handles everything from basic weekly chemical maintenance on newer salt pools to comprehensive service on 30-year-old plaster pools with original equipment. Located just 10 miles from our Northlake headquarters, Lewisville is efficiently served with multiple weekly routes.

Lewisville water profile

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.

Lewisville pool & equipment mix

Lewisville has the widest diversity of pool types in our service area. Established neighborhoods (1980s-2000s) contain classic plaster pools with sand filters and single-speed pumps — many approaching or past equipment replacement age. Newer communities like Castle Hills feature modern installations with pebble finishes, cartridge filtration, variable-speed pumps, and smart automation. Mid-range neighborhoods often have pools in the 15-20 year old range that benefit from targeted equipment upgrades. Pool sizes range from compact 8,000-gallon backyard pools to large 30,000+ gallon installations.

Lewisville high CYA pool correction questions

How fast can you get to my Lewisville pool for high CYA pool correction?
Our usual Lewisville response time is 24-48 hours after the first call, and we're already routing through Denton County most days. Diagnostic visits are scheduled within 1-2 business days.
Does Lewisville water affect high CYA pool correction?
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. For high CYA pool correction that's mostly good news — the failures we see in Lewisville are heat-cycle and chemistry-drift related rather than mineral, so they're more predictable and cheaper to stay ahead of. Most Lewisville pools are plaster or pebble — finishes that show staining fast if chemistry slips.
Do you charge for the diagnostic visit even if I don't book the repair?
Yes — there's a flat diagnostic charge that we quote on the call before we send a tech. We waive it if you book the repair on the same visit. The diagnostic includes a written estimate so you can compare or get a second opinion before any work starts. We don't publish a fixed repair price online because every job is genuinely different — but you'll never get a surprise number.
Are you licensed and insured for pool work in Lewisville?
Yes — we carry full general liability + workers' comp, and our techs are trained on every major brand (Pentair, Hayward, Jandy, Sta-Rite). We're a real local business in Argyle serving Lewisville (75029, 75056, 75057, 75067), not a referral marketplace that sells your details to whoever answers first.
Do you bring parts on the first visit, or do I wait for a second visit for the repair?
We stock the most-common parts on every truck — pump seals, basket lids, cartridges, sand, filter o-rings, ignition components, salt-cell test kits. About 70% of repairs in Lewisville finish on the first visit. The other 30% need a part order; we book the return for the next available slot, usually within 48 hours.
What does high CYA do in a pool?
Cyanuric acid holds free chlorine in reserve to protect it from degradation by sunlight, but high stabilizer slows down sanitizing activity. Above the ideal 30–50 ppm range, the pool requires much higher free chlorine concentrations (at least 7.5% of the CYA level) to prevent algae and sanitize water.
What is the correct cyanuric acid level for a swimming pool?
The target cyanuric acid level is 30–50 ppm. When stabilizer exceeds this range, chlorine binds too strongly, requiring significantly elevated free chlorine levels to maintain clean, safe water.
Why did my CYA get so high?
Standard trichlor tablets and granular dichlor shock continuously add stabilizer alongside chlorine. Trichlor adds about 6 ppm CYA per 10 ppm free chlorine, while dichlor adds about 9 ppm CYA per 10 ppm free chlorine. Because cyanuric acid does not evaporate, routine tablet and shock use causes it to accumulate over time.
Can high CYA be lowered without draining pool water?
No chemical product reliably breaks down or removes cyanuric acid in field conditions. A calculated, staged drain-and-refill with fresh water is the only reliable method to bring stabilizer back into the 30–50 ppm range.

What it covers (12 months · 76 tasks · 12 marked critical):

  • Freeze nights (January and December): keep the pump running, and what to drain if the power goes out
  • The March opening: test everything, brush, shock, then balance alkalinity, pH and calcium
  • Summer: testing two or three times a week, the weekly shock, and what to do after rain or a party
  • Fall leaves, and easing the chemistry down for winter
