Keep Your Pool Water Perfectly Balanced

Balanced water chemistry prevents corrosion, scaling, and algae, ensuring a safe, enjoyable experience and protecting your pool.

Why Water Chemistry Matters

Proper water chemistry prevents skin and eye irritation, often caused by high acidity or chlorine levels. It also ensures your pool equipment runs efficiently, reducing wear and tear on the pump, filter, and heater.

Imbalanced water can create a host of problems. Algae blooms can turn your pool green and slimy, making swimming unsafe. Cloudy water, often caused by incorrect chemical levels, can obscure the pool floor and be unattractive. Additionally, unbalanced water can damage the pool surface and equipment, leading to costly repairs.

How to Balance pH Levels

pH measures how acidic or alkaline your pool water is. The ideal range is typically between 7.2 and 7.6, which ensures chlorine effectiveness and comfort for swimmers.

Here’s how to test and adjust pH levels:

1. Test the Water: Use a reliable pH testing kit to measure the current pH level in your pool water.
2. Adjust as Needed:

• For low pH (acidic) water, you must raise the level by adding a pH increaser like soda ash (sodium carbonate).
• If your water has a high pH (alkaline), lower the level by adding a pH decreaser like muriatic acid or sodium bisulfate.

3. Retest: After adding the necessary chemicals, let the water circulate for several hours. Then, retest to confirm the pH is within the desired range.

Managing Chlorine Levels

Chlorine keeps pool water clean and free from harmful bacteria and algae. The ideal chlorine level is generally between 1 and 3 ppm (parts per million).

Here’s how to manage chlorine levels:

1. Test the Water: Use a chlorine testing kit to measure the current chlorine level.
2. Add Chlorine:

• Low Chlorine: Add liquid, tablet, or granular chlorine. Follow product instructions for dosage.
• High Chlorine: Allow chlorine to dissipate naturally or use a chlorine neutralizer.

3. Shock Treatment: Perform shock treatments periodically to eliminate contaminants and maintain water clarity. This method is best after heavy pool use or heavy rain.

Understanding Alkalinity and Calcium Hardness

Proper alkalinity and calcium hardness levels maintain balanced water chemistry. They help stabilize pH levels and prevent damage to the pool surfaces and equipment.

Alkalinity

Total alkalinity acts as a buffer for pH, preventing sudden fluctuations. The ideal range for total alkalinity in pool water is between 80-120 ppm.

Use a testing kit to measure the current alkalinity level and determine if adjustments are necessary.

Add baking soda (sodium bicarbonate) to increase alkalinity. Meanwhile, carefully add muriatic acid to decrease alkalinity without lowering it too much.

After adjustments, circulate the water and retest to ensure levels are within the ideal range.

Calcium Hardness

Calcium hardness affects pool water’s scaling potential. The ideal range is usually between 200 and 400 ppm.

A testing kit is used to determine calcium hardness and the current level.

If the calcium hardness is too low, add a calcium hardness increaser. If levels are too high, partially drain and refill the pool with fresh water to dilute the calcium concentration.

Circulate the water and retest to ensure calcium hardness is within the ideal range.

How to Safeguard Your Pool’s Gelcoat

The gelcoat is the protective, glossy outer layer of your fiberglass pool. Maintaining it ensures your pool’s aesthetic appeal and structural integrity for years.

What Exactly is a Gelcoat?

A gelcoat is a finishing layer applied to fiberglass pools. It provides a smooth, protective, and water-resistant finish. It’s essential for several reasons, including:

• Enhanced Appearance: The gelcoat comes in various colors and finishes, allowing you to customize your pool’s appearance.
• UV Resistance: It shields the pool’s surface from harmful UV rays, preventing fading and deterioration.
• Protection from Damage: The gelcoat protects the underlying fiberglass from water, chemicals, and physical damage, preventing osmosis and other issues.

Top Tips for Protecting Your Gelcoat

Regular maintenance is required to preserve your pool’s gelcoat. Here’s how to keep it in pristine condition:

• Regular Cleaning: Remove dirt, debris, and organic matter with a mild, non-abrasive cleaner designed for fiberglass pools.

• Avoid Harsh Chemicals: While maintaining water chemistry is essential, be cautious about using highly acidic, alkaline cleaners or other harsh chemicals directly on the gelcoat.

• Prevent Scratches: Be mindful of what comes into contact with your pool’s surface. Use pool-specific brushes and vacuum equipment to avoid damaging the gelcoat with abrasive tools or sharp objects.
