Introduction

Welcome to the wonderful world of swim spa ownership! As you settle into enjoying the relaxation and health benefits your swim spa offers, you might encounter some common issues that many owners face. One such issue is the presence of persistent flakes floating around in your otherwise clear water. If you've found yourself wondering what these flakes are and how to get rid of them, you're not alone. This guide will help you understand the possible causes and provide solutions to keep your swim spa water pristine.

What Are These Flakes?

The flakes you're seeing are typically caused by one of two main factors:

Calcium Scale Formation

• Hard Water Issues: If your water source is high in minerals (hard water), calcium and other minerals can precipitate out, forming visible flakes.
• Chemical Imbalance: Imbalanced pH or alkalinity levels can lead to scaling as minerals become less soluble.

Biofilm and Organic Debris

• Biofilm Buildup: Microorganisms can form a slimy layer inside plumbing and on surfaces, which can break off as flakes.
• Product Residues: Accumulation of lotions, oils, and other contaminants introduced by bathers.

Identifying the Cause

Before you can effectively address the issue, it's important to determine the root cause.

• Test Water Hardness: Use a test kit to measure calcium hardness levels. Ideal levels are usually between 150-250 ppm (parts per million).
• Check pH and Alkalinity: Ensure pH levels are between 7.2-7.8 and total alkalinity is within 80-120 ppm.
• Inspect for Biofilm: If chemical levels are balanced, biofilm might be the culprit.

Solutions

1. Balancing Water Chemistry

Adjust Calcium Hardness:

• If levels are high, consider diluting your spa water with softer water.
• Use a calcium reducer product as recommended by manufacturers.

pH and Alkalinity:

• Use pH increasers or decreasers to balance levels.
• Maintain proper alkalinity to prevent pH fluctuations.

2. Removing Existing Flakes

Spa Vacuuming:

• Continue using your spa vacuum to remove visible flakes.
• Manually skim the surface and clean out filters regularly.

Drain and Refill:

• In stubborn cases, drain the spa completely.
• Clean surfaces thoroughly before refilling.

3. Preventing Calcium Scale

Use Scale Inhibitors:

• Add a sequestering agent or scale inhibitor to prevent minerals from precipitating.
• Follow the product instructions for dosage and frequency.

Regular Maintenance:

• Test water weekly to monitor chemical levels.
• Adjust chemicals promptly to maintain balance.

4. Addressing Biofilm

Pipe Cleaning Products:

• Use a plumbing line cleaner designed to remove biofilm.
• Run the spa with the cleaner according to product instructions.

Shock Treatment:

• Perform a shock treatment to kill microorganisms.
• Use either chlorine-based or non-chlorine shock as appropriate.

5. Enhance Filtration

Upgrade Filters:

• Consider high-quality filters for better particle capture.
• Clean or replace filters more frequently if flakes persist.

Preventative Tips

• Shower Before Use: Encourage users to rinse off to reduce contaminants.
• Limit Chemical Introduction: Be cautious with additives and ensure they are spa-safe.
• Cover the Spa: Use a spa cover to prevent debris from entering when not in use.

When to Seek Professional Help

If you've tried these solutions and the flakes continue to appear, it might be time to consult a professional:

Spa Technician:

• They can perform a thorough inspection and provide specialized treatments.

Water Testing Services:

• Professional testing can detect imbalances or contaminants that home kits might miss.

Conclusion

Dealing with persistent flakes in your swim spa can be challenging, but understanding the causes and implementing the right solutions will help you enjoy a clean and inviting spa experience. Regular maintenance and monitoring are key to preventing future issues.
