Gedney Premium Water Care
Protecting Your Backyard Legacy with Advanced Oxidation Technology
The Investment
A custom gunite pool is a $200,000+ architectural asset. Its lifespan depends entirely on the invisible chemical environment within it.
The Northeast Climate Threat
Extreme winter freeze-thaw cycles test the limits of natural masonry and plaster. Structural durability demands absolute water chemistry perfection.
The LSI Imperative
The Langelier Saturation Index (LSI) is the definitive measure of water balance. Unstable LSI causes plaster to pit, etch, or scale, reducing a 20-year finish to a 5-year liability.
The Saltwater Illusion
The Appeal
Salt Chlorine Generators (SCGs) are widely popular for providing a soft water feel and automating chlorine production.
The Reality
They are fundamentally incompatible with high-end gunite construction, premium natural stone, and automatic safety covers.
The Core Issue
Saltwater systems continuously drive chemical instability and introduce harsh chlorides into porous materials, initiating a cycle of structural degradation.
The LSI Teeter-Totter
A saltwater pool never rests at equilibrium - it swings perpetually between two damaging extremes.
The Process
Electrolysis splits salt (NaCl) into chlorine gas and Sodium Hydroxide (NaOH).
The Consequence
Sodium hydroxide is highly alkaline, continuously driving the pool's pH to extreme highs.
The Reaction
To prevent the pool finish from scaling (feeling like sandpaper), owners must dump large volumes of harsh muriatic acid to crash the pH back down.
The Result
This constant chemical whiplash destroys the LSI equilibrium, literally pulling calcium out of the gunite plaster and causing irreversible pitting, checking, and delamination.
Saltwater Attack on Premium Masonry
Saltwater splashes onto the stone.
Water evaporates, leaving salt behind in the pores.
Salt recrystallizes and expands, cracking the stone.
The Vulnerable Materials
Travertine, Limestone, and Bluestone (the staples of Northeast luxury decks) are highly susceptible to chloride intrusion.
Spalling & Pitting
Expanding salt crystals exert massive internal pressure, causing the stone to literally crumble and pit from the inside out.
Efflorescence
Leaves a permanent, chalky white residue on premium decking.
Leeching
Dissolves naturally occurring minerals within the stone, destroying its internal structural integrity.
Mechanical Degradation: The Hidden Financial Risk
The Target
Automatic safety covers are essential for heat retention and safety, but are highly sensitive to corrosive environments.
The Damage Mechanism
The persistent high chloride levels in saltwater pools actively corrode aluminum cover tracks, cables, and stainless-steel bracket mechanisms.
The Impact
Results in catastrophic mechanical failures, cover jamming, and thousands of dollars in premature replacement costs.
The Gold Standard: Advanced Oxidation Process
Nature's Detergent
AOP mimics the earth's atmosphere, where sunlight interacts with water vapor to create the ultimate air-purifying molecules.
The Hydroxyl Radical (•OH)
AOP systems generate highly unstable, negatively charged molecules that act as the most powerful oxidizers available for water treatment.
The Clean End-State
After instantly destroying contaminants, hydroxyl radicals safely convert back into dissolved oxygen (O2) and water (H2O), leaving no chemical residues.
The Power of the Hydroxyl Radical
Unmatched Power
Hydroxyl radicals have the highest oxidation potential of any pool sanitation method.
Microsecond Eradication
Instantly destroys organic lipids, sweat, bacteria, viruses, and highly chlorine-resistant pathogens (like Cryptosporidium).
The Microsecond Pad Loop
Contained Power
100% of the advanced oxidation work takes place entirely within the equipment pad plumbing - never in the pool itself.
Flash Reaction
Because hydroxyl radicals are so highly reactive, they last for only fractions of a second.
Total Surface Protection
Intense oxidation never touches vulnerable tile, grout, stone coping, or plaster.
The Result in the Pool
Zero chemical byproducts. Zero chloramines. Only pristine, polished water is returned to the swimming vessel.
Swimmer Wellness & Bather Comfort
Asthma & Allergy Friendly
Completely destroys chloramines (combined chlorine) - the byproducts associated with respiratory and skin irritation.
Eczema & Skin Safe
Leaves a pristine, silky, freshwater feel that will not dry out hair or cause eczema flare-ups. Red, stinging eyes are eliminated.
Drinking-Water Standards
Allows the pool to operate safely at a microscopic 0.5 to 1.0 ppm chlorine residual (equivalent to standard municipal tap water).
Zero Chemical Odor
Eliminates the "pool smell" entirely, allowing the backyard to smell like nature, not a public aquatic facility.
Synergistic Dual-Barrier AOP
The Technology
A high-capacity wet chamber reactor combining dissolved ozone gas (O3) with germicidal Ultraviolet (UV-C) light.
The Synergy
When the UV-C light hits the ozone within the chamber, it triggers a catalytic reaction, generating a dense, instantaneous cloud of hydroxyl radicals.
Dual-Barrier Protection
The UV-C light provides secondary sterilization by directly disrupting the DNA/RNA of pathogens passing through the chamber.
Direct-Injection Oxygen Radical System
Air Intake
Venturi system pulls in ambient oxygen (O2).
Catalytic Split
Chamber converts O2 into highly reactive atomic oxygen (O1).
Water Injection
O1 is injected into the plumbing, reacting with H2O to form •OH.
Dry Chamber Design
No pool water ever enters the physical system unit, eliminating scaled quartz tubes and wet-chamber fouling.
Ultra-Low Maintenance
Operates via a simple, 5-minute annual cartridge exchange.
Unmatched Efficiency
Produces a steady stream of oxygen radicals without complex oxygen concentrators or desiccant air dryers.
Multi-Wave Hydroxyl Generator
Unmatched Scalability
Engineered for massive, custom water bodies, expansive vanishing edges, and high-flow water features.
Micro-Flocculation Dynamics
The intense radical creation causes microscopic oils, lotions, and heavy metals to instantly clump together.
Exceptional Clarity
This micro-flocculation allows the pool's standard filtration system to easily trap microscopic debris, resulting in unprecedented, diamond-clear water visibility at depths of 10+ feet.
Diamond-clear visibility depth, achieved through micro-flocculation and standard filtration alone.
The Stabilizer: Automated pH Regulation Dosing System
Ending the Rollercoaster
Replaces manual acid pouring with intelligent, micro-dosing automation.
Perfect Equilibrium
Continuously measures ORP and pH, injecting precise, minute doses of acid only when required to maintain perfect LSI neutrality.
Water chemistry in perfect equilibrium
Asset Insurance
The ultimate safeguard for plaster pools, completely eliminating the extreme chemical fluctuations that cause scale build-up and plaster etching.
App-Based Telemetry
Delivers real-time water chemistry data and out-of-range notifications directly to the homeowner and Gedney service technicians.
The Ecosystem Synthesis: Total Asset Protection
Synergistic Operation
Advanced AOP handles the heavy lifting of hyper-oxidation (destroying pathogens and organics in microseconds).
Chemical Anchoring
The Automated pH system simultaneously locks the LSI in place, preventing any architectural degradation.
The Gedney Result
Together, this ecosystem minimizes chlorine demand by up to 50%, completely eliminates salt-induced spalling, protects automatic covers from chloride corrosion, and supports a 20-year lifespan of premium gunite plaster.
The Ultimate Comparison Matrix
Engineering Precision: Gedney Installation Codes
Strict Hydraulic Sequencing
Where each component sits in the hydraulic chain decides whether an AOP system performs for decades or quietly fails. Every Gedney equipment pad is plumbed to a strict internal sequencing standard, developed over years of installations and audited on every build.
De-Gas Integration
Cover-equipped pools add a layer of hydraulic engineering most installers never account for. Our installation standard includes dedicated de-gas integration that protects the cover system and the finish alike.
Variable-Speed Flow Calibration
Radical generation only happens inside a precise flow window. We calibrate every system to the pool's variable-speed hydraulics and isolate competing circuits so that window holds in every season. The specifications live in our installation standards, not on the internet.
At Gedney Pools, we believe a $200,000+ custom build deserves more than standard chemistry. By rejecting the corrosive realities of saltwater and embracing the pure science of Advanced Oxidation, we ensure your family swims in pristine, drinking-quality water - while permanently protecting the structural integrity of your backyard legacy.
