Understanding Water Balance

Maintaining the correct water balance is crucial for several reasons. It ensures that your spa is safe from harmful bacteria, prevents skin and eye irritation, and protects the spa equipment from corrosion and scaling.

How to Do It

Frequency of Testing

  • Test 2-4 times per week using water testing strips or a liquid test kit.

Key Parameters

  • Chlorine: 1.0–3.0 ppm
  • Bromine: 2.0–4.0 ppm
  • pH: 7.4–7.6
  • Total Alkalinity: 80–120 ppm
  • Calcium Hardness: 150–250 ppm


  • Use a water test log to track your results.
  • If you're in an area with water quality issues, consider using a spa pre-filter.

Filter Maintenance

Why It's Important

A clean filter ensures effective water circulation and filtration, which are essential for maintaining water clarity and hygiene.

How to Do It

Cleaning Frequency

  • Clean every 1-2 weeks
  • Replace annually


  • If your spa filter has a pressure gauge, clean it when the pressure rises 8–10 PSI higher than the freshly cleaned pressure reading.
  • Consider having a pair of filters to swap out during cleaning.

Draining and Refilling

Why It's Important

Over time, the water in your spa accumulates contaminants that can be difficult to remove, even with chemicals. Draining and refilling your spa refreshes the water and makes it easier to maintain.

How to Do It


  • Every 3-4 months


  • Turn off all spa equipment and locate the drain plug, usually at the bottom of the spa.
  • Use a chemical cleaner to remove built-up gunk in your pipes before draining.
  • Once emptied, clean the spa surfaces before refilling with fresh water.

Cover Care

Why It's Important

A well-maintained cover keeps heat, water, and chemicals in, while keeping debris and contaminants out. It also prolongs the lifespan of the cover itself.

How to Do It


  • Air out twice per week


  • Use a 10% bleach-to-water solution to clean the cover and prevent mildew.
  • Consider using a spa cover lifter for easy removal and to give the cover a chance to breathe.

Regular Cleaning

Why It's Important

Regular cleaning prevents the buildup of scum, bacteria, and other contaminants, ensuring that your spa remains a healthy and enjoyable environment.

How to Do It


  • Weekly cleaning of surfaces
  • Quarterly deep cleaning


  • Use non-abrasive sponges and detergents to clean the spa shell.
  • For accumulated debris, consider using specialised spa vacuums

Additional Tips

  • Maintain Good Circulation: Ensure your spa runs for 15-20 minutes twice a day.
  • Sanitizer Levels: Keep a good supply of essential chemicals on hand.
  • Shock Your Spa: Make this a regular part of your maintenance schedule.


    1. Test and adjust your spa water balance 2–4 times per week.
    2. Clean the spa filter every 1–2 weeks and replace annually.
    3. Drain and refill your spa every 3–4 months.
    4. Air out the spa cover twice per week.
    5. Stick to a regular cleaning schedule.

    By following these guidelines, you'll ensure that your spa remains a haven of relaxation and cleanliness. For all your spa maintenance needs, remember that Direct Pool Supplies is your one-stop-shop for quality products and expert advice.
