How to Prepare Your Pool for Summer: The Ultimate BioGuard Checklist

As the warmer days arrive across South Africa, it’s time to shift your swimming pool out of its winter lull and get it ready for peak swimming season. Rising ambient temperatures and intense UV light create the perfect conditions for algae growth and rapid chlorine loss—meaning a quick surface skim won’t be enough to ensure safe, inviting water.

 

Preparing your pool for summer requires a structured approach to balance, sanitise, and protect your water before the first swim.

 

1. Clean and Inspect Pool Hardware: Ensure proper circulation before adding any chemicals.

Begin by removing winter covers, clearing leaves from the weir basket, and brushing down the pool walls and floor. Check your pump, pressure gauge, and filter system for any leaks or worn seals.

 

  • Action: Deep-clean your filter media using a dedicated BioGuard filter cleaner to remove grease, oils, and scale buildup accumulated over winter.

2. Top Up Water & Balance the Chemistry: Target key water parameters before sanitising.

Fill the pool up to its normal operating level (halfway up the weir mouth) and run the filter for at least 12 hours. Next, test your water or visit your nearest authorised dealer for a comprehensive water analysis.

 

  • pH Level: Adjust to 7.2 – 7.6 to ensure swimmer comfort and optimise chlorine efficiency.
  • Total Alkalinity (TA): Maintain between 80 – 125 ppm to prevent unpredictable pH fluctuations.
  • Calcium Hardness: Balance to prevent concrete pitting or plaster surface etching.

3. Shock the Water (Oxidise Organic Waste): Destroy dormant contaminants from winter.

Even clear winter water contains microscopic organic debris, combined chlorines (chloramines), and dormant bacteria. A heavy shock treatment destroys built-up contaminants, restores clarity, and resets the water for routine summer maintenance.

 

  • Action: Apply a high-performance BioGuard shock treatment after sunset to allow the chemical to work without UV interference.

4. Establish Your Summer Sanitiser Routine: Maintain 1 to 3 ppm free chlorine continuously.

Higher water temperatures and frequent pool use consume chlorine rapidly. Establish a continuous sanitising regime using long-lasting floating dispensers, slow-dissolving tablets, or premium sanitising granules to maintain a consistent free chlorine level of 1 to 3 ppm.

5. Apply a Preventative Algaecide: Stop algae blooms before they start.

South Africa’s heat waves can turn a clear pool green overnight. Adding a preventative BioGuard algaecide forms a protective barrier against green, black, and mustard algae spores before they take hold on your pool surfaces.

Summer Maintenance Cheat Sheet

Parameter / Action Ideal Target Range Frequency
Free Chlorine 1.0 – 3.0 ppm Test 2–3 times per week
pH Level 7.2 – 7.6 Test weekly
Total Alkalinity 80 – 125 ppm Test monthly
Shock Treatment Organic oxidation Fortnightly (or after heavy rain/use)
Algaecide Preventative dose Monthly

Keep Your Water Ready All Season Long

A small amount of proactive maintenance at the start of spring saves hours of troubleshooting once summer hits full swing. By balancing your water early, protecting your equipment, and establishing a consistent 3-step routine (Sanitise, Shock, and Prevent Algae), you ensure your pool stays healthy, clear, and ready for every swim.
