Maintaining a spa’s water chemistry in pristine condition is essential for a safe, enjoyable, and hygienic experience. However, even with regular maintenance, chemical imbalances can arise. Below, the Spa Trade Group team offers practical advice on identifying and resolving common spa chemical issues, ensuring your spa water remains clear, balanced, and inviting.
Understanding water chemical chemistry
Understanding the balance between pH, alkalinity, and sanitizer levels is at the heart of spa maintenance. An imbalance can lead to cloudy water, skin irritations, and even damage to your spa equipment. Regular testing with reliable water testing kits is vital. By familiarising yourself with the ideal ranges for each chemical parameter, you can detect issues early before they escalate.
Common issues
1. High or Low pH Levels
- High pH: Water that is too alkaline can result in scaling on surfaces and reduced effectiveness of sanitising agents.
- Low pH: Acidic water can cause corrosion of spa equipment and discomfort to your skin.
2. Imbalanced Alkalinity
Alkalinity acts as a buffer for pH. Low alkalinity may lead to rapid fluctuations in pH, while high alkalinity can result in cloudy water and make it difficult to adjust pH levels.
3. Inadequate Sanitiser Levels
Sanitisers, such as chlorine or bromine, are crucial for keeping the water free from harmful bacteria and algae. Insufficient sanitiser levels can compromise water quality and safety.
4. Cloudy Water
Cloudy water is often a sign of imbalanced chemicals or the presence of contaminants. It could be due to a combination of high organic waste and improper chemical dosing.
Resolve chemical imbalances
Regular testing
- Test Frequently: Aim to test your spa water at least twice a week, or more often during periods of heavy use. Adjust chemical levels promptly according to test results.
- Use Quality Kits: Invest in a reliable test kit that accurately measures pH, alkalinity, and sanitiser levels.
Adjusting pH
- For High pH: Use a pH decreaser (acid) to bring the levels back within the recommended range (typically between 7.2 and 7.8).
- For Low pH: A pH increaser (base) can help restore balance.
- Alkalinity Adjusters: If alkalinity is too low, consider adding an alkalinity increaser. Conversely, use an alkalinity decreaser for high levels. Ensure any adjustments are made gradually to prevent sudden changes.
Maintaining sanitiser levels
- Regular Dosing: Consistently add the appropriate amount of sanitiser to maintain effective water treatment. Follow manufacturer guidelines for dosage.
- Shock Treatments: Periodically shock the spa to eliminate contaminants and boost sanitiser efficiency, especially after heavy use or after a prolonged period without cleaning.
Cleaning and filtration
- Clean the Filters: Regularly clean or replace spa filters to ensure optimal performance and reduce the buildup of contaminants.
- Drain and Refill: Occasionally, draining and refilling your spa is necessary to completely remove accumulated chemicals and impurities.
Preventative maintenance
Beyond daily checks, establishing a regular maintenance routine can help avoid many common chemical issues:
- Scheduled Servicing: Set reminders for routine servicing of both water chemistry and mechanical parts.
- Educate Yourself: Stay informed about the latest in spa care and water treatment innovations to continually refine your maintenance practices.
Seek advice
While many chemical imbalances can be rectified with regular maintenance, some issues may require professional attention. If you encounter persistent problems or are unsure about the adjustments, consulting a spa maintenance specialist or reaching out to the Spa Trade Group team can provide tailored solutions.
