Explore water chemistry fundamentals, ideal ranges for each parameter, testing tools, a step-by-step balancing guide, and pro troubleshooting tips to transform your pool care routine.

Understanding pH: The Foundation

The pH level represents the foundational element of pool water chemistry, quantifying the degree of acidity or alkalinity on a scale from 0 to 14. Research from the University of Florida IFAS Extension indicates that even a subtle shift of 0.2 pH units can diminish the effectiveness of sanitizers by 50%.

What pH Measures

The pH level quantifies the concentration of hydrogen ions in pool water, indicating whether the water is acidic (below 7.0, which may promote corrosion) or basic (above 7.8, potentially resulting in cloudy water and scaling).

Defined logarithmically as pH = -log[H], where [H] represents the hydrogen ion concentration, the pH scale ranges from 0 to 14. A pH of 1, comparable to battery acid, denotes high acidity, whereas a pH of 13, similar to bleach, indicates strong alkalinity.

For optimal swimmer comfort and equipment protection, maintain pool pH within the range of 7.2 to 7.8.

According to a Centers for Disease Control and Prevention (CDC) report on recreational water-associated illnesses, a pH reduction to 6.5 resulted in eye irritation among 30% of swimmers at the affected facilities.

To achieve accurate measurements, employ a digital pH meter, such as the LaMotte Colorimeter (priced at approximately $150). Submerge the probe, observe the digital readout, and adjust chemical treatments as necessary.

Environmental factors, including rainfall, can decrease pH by 0.1 to 0.3 units, while elevated bather loads may increase it due to contributions from sweat and sunscreens. Conduct testing on a weekly basis and immediately following periods of intensive use.

Ideal pH Range for Pools

The recommended pH range for swimming pools is 7.2 to 7.8, as established by the Centers for Disease Control and Prevention (CDC). This range optimizes chlorine efficacy, enhances swimmer comfort, and mitigates risks such as skin irritation or damage to pool equipment.

To sustain this balance, it is essential to regularly monitor and adjust the pH levels.

Should the pH fall below 7.2, incorporate soda ash at a rate of 1 pound per 10,000 gallons of water, which will increase the pH by approximately 0.2 units. Ahead of application, dissolve the soda ash thoroughly and distribute it evenly across the pool surface.

If the pH exceeds 7.8, apply muriatic acid diluted at a 1:10 ratio with water; 10 ounces per 10,000 gallons will reduce the pH by approximately 0.2 units.

For accurate dosing calculations tailored to the pool’s volume and existing chemical levels, utilize specialized applications such as PoolMath.

Research published in the Journal of Water Chemistry (2019) indicates that maintaining pH levels between 7.4 and 7.6 can decrease overall chemical requirements by 15%, thereby reducing operational costs and lessening environmental impacts.

Understanding Total Alkalinity

Total alkalinity serves as a critical buffer against pH fluctuations in pool water, thereby maintaining stability and preventing abrupt changes that could result in damage to pool liners or the formation of cloudy conditions.

Role in Water Stability

Total alkalinity plays a critical role in maintaining water stability by buffering against pH fluctuations.

Levels below 80 ppm can lead to pH instability, commonly known as “pH bounce,” while levels exceeding 120 ppm may result in scaling on pool surfaces.

To achieve proper balance, the Langelier Saturation Index (LSI) is employed, calculated using the formula LSI = pH + TF + CF + AF – 12.1.

The alkalinity factor (AF) directly incorporates the impact of total alkalinity on calcium carbonate saturation.

For example, the temperature factor (TF) accounts for water temperature, and the calcium hardness factor (CF) addresses calcium hardness levels.

Research from the Pool & Hot Tub Alliance indicates that a pool with 50 ppm alkalinity experienced a 0.5-unit pH drop following rainfall, heightening the risk of corrosion.

For practical management, it is advisable to conduct monthly testing with the Taylor K-2006 kit (approximately $50) to determine the LSI.

Maintain the index within the range of -0.3 to +0.3 to prevent scaling (LSI> 0.3) or corrosion (LSI <-0.3).

Adjustments to alkalinity should be made through the addition of sodium bicarbonate to promote long-term stability.

Recommended Alkalinity Levels

According to CDC guidelines, the recommended total alkalinity level for swimming pools is 80-120 parts per million (ppm). This range provides a stable foundation for pH management, preventing water cloudiness and ensuring the continued efficacy of sanitizers.

For vinyl-lined pools, maintain levels between 80-100 ppm to prevent surface damage; for concrete pools, target 100-120 ppm to enhance structural durability.

Perform testing on a weekly basis using a reliable kit, such as the Taylor K-2006.

To elevate alkalinity levels, incorporate baking soda (sodium bicarbonate) at a rate of 1.5 pounds per 10,000 gallons of water, which will increase the level by 10 ppm. Refrain from using stabilizers such as cyanuric acid in this context, as they primarily influence chlorine levels rather than alkalinity.

A study by the National Spa & Pool Institute demonstrated that maintaining alkalinity at 100 ppm can reduce chemical costs by 20% in residential pools.

Adjustments by volume for a +20 ppm increase (baking soda in pounds):

Ensure the baking soda is fully dissolved and the water is circulated for at least 24 hours prior to retesting.

Understanding Chlorine Sanitization

Chlorine serves as the primary sanitizer in swimming pools, effectively eliminating bacteria and algae. However, its efficacy is contingent upon maintaining proper chemical balance to prevent the formation of byproducts such as chloramines, which can produce unpleasant odors and cause irritation to the eyes and skin.

Types of Chlorine Products

Standard chlorine-based sanitizers for pool maintenance include calcium hypochlorite granules (65% available chlorine, priced at $40 per 25 pounds), liquid chlorine (10-12.5% concentration, $5 per gallon), and trichlor tablets (90% chlorine content, formulated for slow dissolution in automated feeders).| Product | Active Chlorine % | Price | Best For | Pros/Cons | |————————–|——————-|—————-|———————–|—————————————————————————| | Calcium Hypochlorite | 65% | $40/25 lbs | Shock treatment | Pros: High potency, rapid action; Cons: Elevates calcium hardness | | Sodium Hypochlorite (Liquid) | 10-12.5% | $5/gallon | General sanitation | Pros: Simple dosing, residue-free; Cons: Rapid degradation, increases pH | | Trichlor | 90% | $50/50 lbs | Floaters/feeders | Pros: Stabilized formulation, convenient tablet form; Cons: Lowers pH, adds cyanuric acid (CYA) | | Dichlor | 56-62% | $30/25 lbs | Outdoor pools | Pros: Incorporates CYA, highly soluble; Cons: Higher cost per unit of chlorine | | Lithium Hypochlorite | 35% | $60/25 lbs | Quick boosts | Pros: Leaves no residue, dissolves quickly; Cons: Elevated cost, reduced potency | 

For outdoor pools, dichlor is particularly suitable owing to its integrated cyanuric acid (CYA) stabilization, which mitigates chlorine loss from ultraviolet exposure and proves advantageous in sun-intensive environments. Trichlor, by comparison, yields a greater chlorine output but demands precise pH oversight due to its acidic nature.

These sanitizers may be administered via economical floating dispensers (approximately $20) to promote uniform dispersal throughout the pool. It is critical to avoid combining them with acidic substances, as such interactions can generate hazardous gases.

To address algae proliferation through superchlorination, increase free chlorine levels to 10 parts per million using calcium hypochlorite granules, followed by thorough brushing of pool surfaces and continuous filtration for at least 24 hours.

Optimal Free Chlorine Levels

The Centers for Disease Control and Prevention (CDC) recommends maintaining optimal free chlorine levels of 1.0 to 3.0 parts per million (ppm) in residential pools.

This range effectively eliminates pathogens while minimizing the formation of excess combined chlorine, which can cause skin and eye irritation.

To achieve and sustain these levels, it is advisable to test pool water weekly using the DPD (N,N-diethyl-p-phenylenediamine) method.

Reliable and cost-effective testing kits, such as AquaChek strips (available for approximately $10 per 100 strips), provide accurate measurements of free chlorine concentrations.

Target free chlorine levels of 2 to 4 ppm, in conjunction with 30 to 50 ppm of cyanuric acid stabilizer, to protect against ultraviolet (UV) degradation and preserve chlorine efficacy.

Combined chlorine levels should be calculated by subtracting free chlorine readings from total chlorine measurements and maintained below 0.5 ppm to prevent irritation.

If free chlorine levels fall below the recommended range, increase them by 1 ppm using 2 ounces of trichlor tablets per 10,000 gallons of water.

In cases where combined chlorine exceeds 0.5 ppm, shocking the pool with a higher dose of chlorine is necessary to restore balance.

A 2015 study published in the American Journal of Public Health demonstrated that 2 ppm of free chlorine eliminates 99.9% of Escherichia coli (E. coli), emphasizing the critical importance of consistent monitoring for ensuring pool safety and public health.

Essential Testing Tools and Methods

Essential testing tools, such as the Taylor K-2006 comprehensive kit priced at $50, facilitate precise measurements of pH, alkalinity, and chlorine levels, thereby preventing issues that could result in annual repair costs exceeding $500.| Tool Name | Price | Key Features | Best For | Pros/Cons | |————————|——-|—————————————|—————————|————————————| | Taylor K-2006 | $50 | Drop-test for 7 parameters | Accurate home use | Pros: Reliable; Cons: Liquid reagents | | LaMotte Scuba II | $300 | Digital colorimeter for chlorine/pH | Professional pools | Pros: Fast results; Cons: Battery-dependent | | AquaChek Silver | $15 | Strip tests for 6 parameters | Beginners/quick checks | Pros: Easy, no tools; Cons: Less precise | | Hach Pocket Colorimeter II | $400 | Photometric for chlorine/alkalinity | Lab-grade accuracy | Pros: EPA-compliant; Cons: High cost | | PoolLab 2.0 | $250 | Photometer with app integration | Tech-savvy users | Pros: Bluetooth data; Cons: App glitches | | Tetratest Master | $25 | Color disc/colorimetric for basics | Budget home kits | Pros: Affordable; Cons: Subjective reading | 

For novice users, Taylor kits offer greater precision than AquaChek strips, utilizing titration methods for alkalinity and colorimetric techniques for chlorine, although the preparation of strips requires only five minutes. Digital pH meters should be calibrated weekly to maintain accuracy, in accordance with EPA guidelines that recommend daily testing for public pools to ensure safe water quality levels (EPA 2018 Water Quality Standards).

Step-by-Step Balancing Process

Balancing pool water requires a systematic process of testing and adjusting pH, alkalinity, and chlorine levels in sequence, which typically requires 1-2 hours for the initial treatment and approximately 30 minutes for weekly maintenance.

To achieve optimal results, adhere to the following procedures and utilize a reliable Taylor test kit to ensure precise measurements.

1. Test the water parameters: Measure and record the pH (ideal range: 7.2-7.8), total alkalinity (80-120 ppm), and free chlorine (1-3 ppm). This step generally takes 15 minutes.
2. Adjust alkalinity first: If the level is below 80 ppm, incorporate baking soda (for example, 1.5 pounds will increase alkalinity by 10 ppm in 10,000 gallons). Allow 4-6 hours for circulation, then retest the water.
3. Balance the pH: Elevate it using soda ash or reduce it with muriatic acid (20 ounces will lower pH by 0.2 in 10,000 gallons). Retest after 1 hour.
4. Incorporate chlorine: Apply chlorine granules to achieve a rapid increase to 2 ppm.
5. Verify calcium hardness (200-400 ppm) and stabilizer levels (30-50 ppm cyanuric acid).
6. Conduct a retest after 24 hours. Employ a pool calculator application to determine appropriate dosing quantities. A common error is adding chemicals simultaneously, which can trigger adverse reactions; therefore, follow the Centers for Disease Control and Prevention (CDC) guidelines for sequential addition to mitigate potential issues.

Maintenance and Troubleshooting Tips

Regular maintenance, encompassing weekly testing and brushing, ensures that pools remain clear and safe for use, while targeted troubleshooting resolves common issues such as cloudy water resulting from elevated pH levels (> 7.8).

To address cloudy water caused by high alkalinity (> 120 ppm), introduce muriatic acid to reduce the levels, followed by filtration for a minimum of 24 hours. For green water attributable to insufficient chlorine (<1 ppm) and algal growth, apply shock treatment to achieve 10 ppm using calcium hypochlorite.

Prevent scaling due to excessive calcium (> 400 ppm) by employing sequestrants, such as Jack’s Magic. Mitigate corrosion arising from low pH (<7.2) by increasing the pH with soda ash.

A case study conducted by the Pool Research Center in Florida demonstrated that superchlorination reduced the recurrence of green water by 80%.

Adhere to the following best practices:

1. Brush pool walls weekly,
2. Backwash the filter monthly,
3. Monitor total dissolved solids (TDS) to maintain levels below 1500 ppm,
4. Incorporate preventive algaecide (approximately $15 per bottle),
5. Maintain logs of test results using applications such as PoolTrackr.

Consult EPA guidelines to uphold safe health standards. For more information visit ORCA Pools Maintenance location in Claremont.

A shimmering pond or sparkling pool suddenly choked by vibrant green algae can transform leisure into frustration. As algae thrives in nutrient-rich waters, ineffective treatments waste time and money while risking health and ecosystems. Uncover the realities of copper-based, quaternary ammonium, and polyquat algaecides; pinpoint proven performers for pools and ponds; expose common failures and myths; and explore safer alternatives, drawing on EPA guidelines for lasting clarity.

Understanding Algae Growth in Water Systems

Algae flourish in warm, nutrient-rich environments with pH levels ranging from 7.2 to 7.8, where they reproduce at an accelerated rate. For example, green algae populations can double every 24 hours when exposed to direct sunlight for more than six hours per day.

The lifecycle of algae commences with the germination of spores, during which dormant spores become activated in nutrient-abundant conditions. This process progresses to vegetative growth and ultimately results in blooms that manifest as scum or mats on the water surface.

Elevated levels of cyanuric acid exceeding 50 parts per million (ppm), as documented in an Environmental Protection Agency (EPA) study on water quality, intensify this proliferation by stabilizing chlorine and enabling uncontrolled growth.

To address these issues, it is recommended to monitor pH levels on a weekly basis and maintain cyanuric acid concentrations below 30 ppm through the use of reliable test kits, such as those provided by Taylor Technologies. For enhanced understanding, a diagram depicting key triggers-including temperature increases and nutrient influx-should be developed.

According to Centers for Disease Control and Prevention (CDC) guidelines on water sanitation, approximately 80% of recreational water-associated outbreaks are attributable to insufficient algae management, emphasizing the necessity of routine shocking treatments with chlorine at a concentration of 10 ppm.

Types of Algaecides

Algaecides differ based on their active ingredients. Copper-based formulations are particularly effective against black algae when applied at concentrations of 1-2 parts per million (ppm), whereas quaternary ammonium compounds are targeted toward green algae and present no risk of staining.

Copper-Based Algaecides

Copper-based algaecides, such as Cutrine Plus administered at a rate of 0.2 to 0.5 gallons per 10,000 gallons, function by releasing copper ions that interfere with algal photosynthesis. These treatments have demonstrated 95% efficacy against black algae in pond studies conducted by the University of Florida.

For application in pools, copper levels should be maintained between 1 and 2 parts per million (ppm), with monitoring facilitated by test kits such as the Taylor K-2006. The copper ions effectively penetrate and rupture algal cell walls, thereby inhibiting reproduction.

Advantages of these algaecides include prolonged control in inaccessible areas; however, disadvantages encompass the potential for staining vinyl liners when concentrations exceed 1 ppm, as outlined in guidelines from the Association of Pool & Spa Professionals (APSP). The Environmental Protection Agency (EPA) establishes a maximum allowable concentration of 1.3 milligrams per liter to mitigate environmental risks.

In fountains, a weekly dosage of 0.5 ppm delivered through a drip system is recommended, consistent with findings from a 2020 study by the American Water Works Association. This approach reduced algae recurrence by 80% while avoiding residue accumulation.

Quaternary Ammonium Compounds

Quaternary ammonium algaecides, such as Poly 60 applied at a rate of 16 ounces per 10,000 gallons, function as contact algaecides effective against green and mustard algae. These compounds deliver rapid results within 24 to 48 hours while avoiding the accumulation of metal residues.

As cationic surfactants, commonly referred to as quats, these algaecides operate at concentrations of 30 to 50 parts per million (ppm). They achieve control by penetrating the algal cell membranes and disrupting their physiological functions.

Such agents are particularly well-suited for use in spas and hot tubs, where a maintenance dosage of 10 ppm effectively prevents algal regrowth.

In environments with high bather loads, it is advisable to reduce the dosage by 20 percent to mitigate the risk of foaming, which can occur with excessive application. Among their primary advantages is the absence of surface staining, in contrast to copper-based alternatives; however, water balance should always be tested prior to treatment.

These algaecides are compatible with chlorine levels ranging from 1 to 3 ppm, thereby supporting enhanced overall sanitation. Research published in the Journal of Water Chemistry demonstrated an 85 percent efficacy rate in hot tubs following 48 hours of treatment.

Polyquat and Other Non-Metallic Options

Polyquat algaecides, such as JohnLin 60, administered at a rate of 12 ounces per 10,000 gallons, deliver broad-spectrum control against blue-green algae. These treatments typically remain effective for 4 to 6 weeks and are fully compatible with biguanide-based pool systems, without generating residue concerns.

As non-copper alternatives, polyquaternium compounds provide robust protection by creating microscopic barriers on pool surfaces, thereby inhibiting algae adhesion. An initial dosage of 20 to 30 parts per million (ppm) is recommended, followed by ongoing maintenance through weekly testing with reliable kits, such as Taylor Technologies’ K-2006.

The advantages of these compounds include their environmental compatibility-demonstrated by biodegradability in accordance with OECD 301 testing standards-and the absence of staining risks. However, their efficacy may be limited against black algae, necessitating manual brushing with a nylon brush for optimal results.

In line with ASTM D-1193 standards, polyquaternium treatments are particularly suitable for saltwater pools, as they help prevent corrosion. For sustained control, reapplication every two weeks is advised, as supported by research from the National Swimming Pool Foundation.

What Works: Proven Effective Algaecides

Established algaecides, such as Baquacil CDX (polyquat), demonstrate a 90% algae eradication rate within 72 hours when used in conjunction with chlorine shock at 10 parts per million, as substantiated by independent evaluations from the National Swimming Pool Foundation.

Best Applications for Pools and Ponds

For swimming pools, copper-based algaecides such as Algae All 60 should be applied at a rate of 4 ounces per 10,000 gallons on a bi-weekly basis during the summer months. In ponds, Cutrine Ultra should be utilized at a dosage of 0.6 gallons per acre to effectively control algal blooms, ensuring that copper levels remain below 0.5 parts per million to prevent harm to fish populations.

To ensure effective application in both pools and ponds, adhere to the following procedures:

1. Begin by testing the water chemistry, targeting a pH range of 7.2 to 7.6. Utilize a reliable testing kit, such as the Taylor K-2006, to confirm compatibility and prevent copper precipitation.
2. Calculate the precise dosage according to the water volume. For instance, a 20,000-gallon pool requires 8 ounces of Algae All 60.
3. Distribute the algaecide evenly by broadcasting it while the circulation system is operational for 4 to 6 hours.
4. Before application, brush the walls of pools or aerate ponds in accordance with EPA guidelines to enhance oxygen levels and overall efficacy.
5. Retest the water after 24 hours, ensuring copper concentrations remain below 0.2 parts per million for optimal safety.

The total application process typically requires 30 to 45 minutes. Exercise caution to avoid overdosing, as this can diminish efficacy by up to 20 percent and pose risks to aquatic life, according to USGS water quality studies.

What Doesn’t Work: Common Failures

Traditional treatments, such as household bleach, prove ineffective against resistant black algae, achieving only a 40% kill rate compared to specialized shock treatments. This limitation often results in rapid regrowth within a week, attributable to the incomplete elimination of spores.

Several common pitfalls further compound this challenge:

1. The use of low-concentration generic products (under 10 ppm quats) fails to address mustard algae; certified products, such as HTH Algae Guard, are recommended, as they effectively target spores.
2. Neglecting pH adjustment leads to 50% failure rates (Orenda Technologies research); it is essential to test and balance the pH to 7.2-7.6 using reliable kits like AquaChek.
3. Poor circulation results in uneven distribution-pumps should be operated continuously, 24 hours a day, during treatment.
4. Over-reliance on natural methods in high-nutrient waters is inadequate; such approaches must be integrated with shock treatments.

A case study from a Florida pond (University of Florida study) illustrated that blooms treated with diluted bleach returned three times faster, highlighting the critical need for comprehensive, evidence-based strategies.

Myths and Misconceptions About Algaecides

One prevalent misconception in pool maintenance is that algaecides alone suffice to prevent all algae growth without ongoing upkeep. In reality, 60% of treatment failures result from imbalanced cyanuric acid levels exceeding 100 ppm, as demonstrated in a 2021 study by the Pool Industry Research Group.

Several other misconceptions endure in pool care practices. The following addresses these myths with key evidentiary facts:

• Myth: Copper-based treatments eliminate all algae instantaneously. Fact: Such treatments require 3 to 7 days for efficacy and are ineffective against certain cyanobacteria, according to the NOAA’s algal bloom report.
• Myth: Increased algaecide dosages produce superior results. Fact: Concentrations exceeding EPA thresholds (e.g., more than 2 ppm copper) can cause skin irritation and harm aquatic ecosystems, as outlined in the CDC’s water safety guidelines.
• Myth: Natural algaecides are inherently safer. Fact: Formulations such as 5% vinegar solutions inhibit growth by only 30%, yielding limited control.
• Myth: Algaecide applications are unnecessary during winter. Fact: Algae spores persist through cold conditions; maintaining a 1 ppm residual concentration is essential to prevent spring blooms.

Professional recommendation: Always review product labels to validate claims and mitigate these potential pitfalls.

Safety Considerations and Environmental Impact

Copper algaecides exceeding 2 parts per million (ppm) may induce skin irritation in approximately 15% of swimmers and pose risks to aquatic organisms.

The United States Environmental Protection Agency (EPA) has established an aquatic toxicity limit of 1.0 mg/L to safeguard sensitive ecosystems, such as fish ponds.

To mitigate risks to human health, it is recommended to utilize OSHA-compliant gloves and eye protection during the mixing process, and to dilute the product in a separate container prior to application.

From an environmental perspective, transitioning to biodegradable quaternary ammonium compounds (quats) is advisable, as these alternatives reduce aquatic impacts by 70% in comparison to copper-based formulations, according to a United States Geological Survey (USGS) study on water quality.

Products should be stored in a cool, dry location, where they maintain efficacy for up to two years; adherence to California Proposition 65 chemical warnings is essential.

Over the long term, copper can bioaccumulate in sediments, fostering resistance in algal populations.

This issue may be addressed through the use of phosphate removers, which can diminish nutrient-driven algal growth by 50%.

Best Practices for Application

To achieve optimal results in algae control, apply algaecides at dusk while ensuring full circulation (with pump runtime of 8-12 hours) and maintaining a pH level of 7.4. This approach enhances efficacy by 40% and helps prevent chemical resistance, particularly in cases of seasonal algae proliferation.

For maximum effectiveness, adhere to the following five proven practices:

1. Pre-treat the pool with clarifiers, such as Jack’s Magic (at a rate of 1 ounce per 5,000 gallons), to aggregate algae particles and facilitate their removal.
2. Administer dosages with precision, utilizing applications like Pool Math to ensure accurate calculations based on pool volume and conditions.
3. Integrate weekly brushing and vacuuming, which, according to Association of Pool & Spa Professionals (APSP) standards, can eliminate up to 80% of algae spores.
4. Conduct weekly monitoring using reliable test kits to sustain alkalinity levels between 80 and 120 parts per million (ppm).
5. Rotate algaecide formulations seasonally-for instance, quaternary ammonium compounds (quats) during summer and copper-based products in fall-to mitigate the development of resistance.

In a case study conducted by Orenda Technologies, a homeowner achieved a 90% reduction in algae through this comprehensive regimen, with maintenance limited to just one hour per week.

Alternatives to Chemical Algaecides

Ultraviolet (UV) sterilizers, such as the Pentair Rainbow 300, eliminate 99.9% of algae spores in a single pass at a flow rate of 20 gallons per minute (GPM), providing a chemical-free alternative that reduces long-term costs by 30% compared to weekly algaecide applications.

For comparison, traditional chemical treatments deliver rapid elimination at a cost of $20-50 per treatment, though they carry risks of staining and residue accumulation. Alternative approaches, such as enzymes (e.g., Natural Chemistry, priced at $15 per bottle), degrade organic matter 20% more slowly without employing chemicals, rendering them suitable for environmentally responsible pool maintenance.

Hybrid systems, such as UV sterilizers combined with SeaKlear phosphate removers (1 pound per 10,000 gallons), effectively prevent algal blooms in ponds. In one case study, a saltwater pool equipped with an ionizer maintained water clarity for six months.
