At Weston Pools LLC, we believe a beautiful, inviting pool starts with balanced water chemistry. Your pool water isn't just H₂O—it's engineered to be safe, comfortable, and synergistic with your body. Just like we care for our own health, the pool needs proper care to stay free of bacteria, algae, and contaminants while remaining crystal clear and enjoyable.

We treat water to meet specific standards: ideal ranges for pH, chlorine, calcium hardness, cyanuric acid (CYA), and more. Proper balance prevents issues like cloudy water, equipment damage, or health risks.

Chlorine: The Essential Sanitizer

A common question we hear: "Why can't they just sell regular chlorine?"

Chlorine gas is the purest form, but it's impractical and dangerous for home use. To make chlorine stable and easy to handle:

  • Calcium Hypochlorite (Cal-Hypo) adds calcium.

  • Trichlor tablets and Dichlor add cyanuric acid (CYA/stabilizer).

  • Liquid chlorine (bleach) is sodium hypochlorite, diluted in water.

All forms are effective when used correctly—no one is "impure." The key is choosing the right type for your pool and maintaining balance. We recommend unstabilized chlorine (like liquid) in many cases to avoid CYA buildup.

Mineral Purifiers and Natural Assistance

Ever notice how mall fountains stay crystal clear with just circulation? Many use copper (a natural algaecide). Products like Nature2, Frog, or Pool RX incorporate minerals (copper/silver) to reduce chemical needs and help control algae for up to 6 months. These are excellent supplements but not full replacements for sanitizer.

Bather Load, Chloramines, and Contaminants

"Bather load" refers to how many people (and what they bring) affect the water:

  • Sweat, urine, sunscreens, lotions, and hair products react with chlorine to form chloramines—the "chlorine smell" culprit.

  • Chloramines reduce free chlorine's effectiveness and cause eye/skin irritation.

  • Solution: Maintain proper free chlorine levels and shock (breakpoint chlorination) regularly to eliminate them. More bathers = more frequent testing/adjustments.

Pets in the Pool? One dog can introduce as much debris, oils, and contaminants as several humans—leading to faster filter clogs and chemistry shifts. Rinse pets before swimming and clean filters more often.

Saltwater Systems (Chlorine Generators)

Salt systems electrolyze salt (sodium chloride) to produce chlorine gas on-demand—creating softer, gentler water many love.

Pros:

  • Softer feel on skin/eyes/hair.

  • No strong chlorine odor.

  • Convenient (less manual dosing).

Cons & Maintenance:

  • Generates sodium hydroxide, raising pH—requires weekly pH checks and acid additions.

  • Salt cells cost ~$1,000+ to replace (can fail if not cleaned quarterly).

  • Corrosion risk to equipment if pH drifts high.

Salt pools aren't "set it and forget it"—they need consistent attention, especially pH. Many owners find the soft water worth it, but weigh the costs.

Calcium Hardness: Protecting Your Pool Surface

Calcium hardness (CH) prevents water from becoming aggressive (pulling minerals from surfaces) or scaling.

  • Ideal range (plaster/gunite pools): 200–400 ppm.

  • North Texas tap water (Collin County area) is often low in calcium, so additions are common for new pools.

  • Low CH causes etching on plaster, efflorescence (white deposits from grout/tile), or damage to gunite/shell.

  • High CH risks scaling—avoid Cal-Hypo if your water is already hard.

Keep logs! Builders check chemistry records for warranty claims.

Fiberglass Pools: Special Considerations

Fiberglass doesn't contain calcium like plaster, so needs differ:

  • Many manufacturers recommend lower CH (<120–200 ppm) to avoid scaling, chalking, or discoloration on the gelcoat.

  • Water seeks balance—if too aggressive, it can etch fiberglass or fixtures to reach soil minerals.

  • Follow your manufacturer's guidelines closely.

  • Common issues we see: Undersized filters (clean monthly), single skimmer (less surface cleaning), no main drain (stagnant bottom water), visible dirt on smooth surface.

pH: The Most Volatile Factor

pH tends to rise naturally in North Texas pools due to:

  • Rainwater (often alkaline).

  • Bather waste (sweat/urine).

  • Aeration from features/waterfalls.

  • Algae thrives in high pH.

Ideal: 7.4–7.6. High pH reduces chlorine effectiveness and causes scaling/white buildup. Add acid weekly; turn off features temporarily if troubleshooting.

Phosphates: Algae's Favorite Food

Phosphates (measured in ppb, not ppm) come from fertilizers, organics, and debris—fuel for algae.

  • High levels cause cloudiness or saturate the LSI (saturation index).

  • Removers help starve algae but aren't disinfectants—still need chlorine.

  • Controlling phosphates makes algae prevention easier.

Cyanuric Acid (CYA/Stabilizer)

CYA shields chlorine from UV degradation—essential outdoors.

  • Ideal: 30–50 ppm (Texas public pools shut down over 100 ppm).

  • Too high (>100 ppm) "locks" chlorine, making it ineffective against bacteria/algae—pool may look clear but harbor germs.

  • High CYA skews test readings and increases infection risks (e.g., ear issues from swallowed water).

To lower high CYA: Drain and refill (partial drains often aren't enough). Start fresh with new water for best results. Contact your builder first.

Other Reasons to Drain & Refill

  • High Total Dissolved Solids (TDS) (minerals too small for filters).

  • Excessively high calcium/hard water.

Balanced chemistry saves time, money, and headaches—preventing algae, equipment failure, and costly repairs.
