5 Reasons to Keep Your Pool at 78°F

Comfort for moderate swimming At 78°F, your body generates enough heat during swimming to stay comfortable without feeling cold.

Slows algae growth Warmer water above 78°F accelerates algae growth, making your pool harder to maintain.

Reduces chlorine demand Cooler water at 78°F keeps chlorine effective longer, so you use less shock treatment and chemicals.

Saves on heating costs Every degree above 78°F adds 10-15% to your heating bill, making 78°F the most cost-effective temperature.

Balances chemical stability At 78°F, your pool’s chemical balance is easier to maintain than at higher temperatures, saving you time and money.
