Three Things Spike Demand

Heat accelerates reactions, sun burns off chlorine, and more swimmers bring in more organics. If stabilizer is too low, UV loss can be brutal.

The right fix is usually a combination of maintaining target free chlorine for your stabilizer level, improving circulation, and being disciplined about brushing and filtration during hot stretches.

A Simple Summer Routine

Keep it boring and consistent when the weather is intense.

  • Test more often (every 1 to 2 days) during peak heat
  • Brush steps, corners, and benches where algae starts
  • Run the pump longer during the hottest weeks
