What our pool CYA reduction covers in Lewisville

A structured water exchange and stabilizer remediation service for pools locked by excess cyanuric acid. We measure true CYA levels, calculate the exact exchange volume needed, and manage the refill and rebalancing process. Book online or request a quote to get started.

  • ✓Calibrated turbidity testing for accurate CYA measurement beyond standard test-strip limits (up to 150+ ppm)
  • ✓Target dilution modeling to reach the standard 30–50 ppm CYA range based on total pool gallonage
  • ✓Submersible pump setup and high-flow discharge routing to protect surrounding landscape

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

  • • Municipal water utility charges for the fresh refill volume
  • • Complete dry-draining on fiberglass shells or high-groundwater plaster pools without hydrostatic release access
  • • Chemical neutralizer bags (biological CYA reducers), which in our experience yield inconsistent field results compared to water exchange

Common pool CYA reduction symptoms we see in Lewisville

Chlorine lock where test strips show high chlorine but algae keeps growingCYA testing black-dot tube disappearing immediately at 100+ ppmPersistent cloudy water that fails to clear after multiple shock treatmentsStabilizer buildup after seasons of continuous 3-inch trichlor tablet useHigh chemical demand requiring excessive chlorine to maintain a 7.5% free chlorine-to-CYA ratio

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

About pool CYA reduction 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.

"We were paying too much for pool service that wasn't even showing up half the time. Switched to Simplified Pools and immediately noticed the difference — consistent, communicative, and our pool has been crystal clear since day one. The text notifications are a great touch."

Lewisville pool CYA reduction questions

How fast can you get to my Lewisville pool for pool CYA reduction?
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 pool CYA reduction?
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 pool CYA reduction 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.
Why is draining and refilling the standard method to lower CYA?
Cyanuric acid does not evaporate, degrade naturally in normal pool conditions, or filter out through standard media. While enzymatic or biological CYA reduction pouches exist on the retail market, in our experience they require precise temperature, pH, and zero-chlorine conditions that make them unreliable in field use. Controlled water replacement remains the standard, predictable method.
How did my pool's CYA get so high?
Standard 3-inch chlorine tablets (trichlor) and granular shock (dichlor) are stabilized sanitizers containing roughly 50% to 55% cyanuric acid by weight. Every pound of trichlor dissolved into your pool permanently adds stabilizer. Over 1 to 2 seasons without substantial splash-out or winter drains, CYA climbs above 100 ppm, binding free chlorine and reducing its sanitizing speed.
How much water needs to be replaced to lower CYA?
CYA dilution is directly proportional to the volume exchanged. If your pool is tested at 100 ppm and the goal is the standard 30–50 ppm range, roughly 50% to 60% of the pool water must be replaced with fresh water. We calculate the exact percentage before beginning to avoid wasting water or over-draining.
Is it safe to drain my pool completely to fix CYA?
We rarely recommend complete dry-drains solely for high CYA. Emptying a pool completely can expose plaster to delamination in Texas heat, float fiberglass shells if groundwater is high, or pop hydrostatic valves. We typically use partial water exchanges or bottom-drain continuous dilution to keep structural weight in the pool.

  • 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
