Swimming Pool Maintenance Guide for Tamil Nadu's Hot Climate

Tamil Nadu's climate — with temperatures averaging 28–38°C and high humidity — creates a demanding environment for swimming pools. Without proper maintenance, a pool can turn green with algae within 48 hours during summer. This guide covers everything you need to keep your pool clean, safe, and sparkling.

Daily Maintenance Tasks

• Test water pH and chlorine levels (ideal pH: 7.2–7.6)
• Run the filtration pump for a minimum of 6–8 hours
• Skim leaves and debris from the surface
• Check and empty the skimmer and pump baskets

Weekly Maintenance

• Brush the pool walls and floor to prevent algae adhesion
• Vacuum the pool floor (manual or automatic cleaner)
• Shock-treat the pool with chlorine (especially after heavy rain)
• Check and balance alkalinity (80–120 ppm) and calcium hardness (200–400 ppm)
• Backwash the filter if pressure is elevated

Dealing with Algae in Tamil Nadu

Green algae is the most common problem pool owners face in Tamil Nadu and Kerala. It thrives when chlorine levels drop below 1 ppm, which can happen rapidly in 35°C+ heat. Here's how to prevent and treat it:

Prevention

• Keep chlorine levels between 1–3 ppm consistently
• Add a weekly dose of algaecide, especially in summer
• Run the pump during the hottest part of the day (10 AM – 4 PM)
• Install a pool cover when not in use to reduce UV degradation of chlorine

Treatment (If Algae Appears)

• Shock the pool with 3–5× the normal chlorine dose
• Brush all surfaces vigorously to dislodge algae
• Run the filter continuously for 24–48 hours
• Add an algaecide after the chlorine level drops below 5 ppm
• Vacuum dead algae off the floor

Annual Professional Service

Once a year, have a professional service your pool equipment — inspect the pump seals, clean the filter media, check all fittings, and test the electrical systems. This prevents costly breakdowns and ensures your equipment lasts its full lifespan.
