How’s the water? You won’t know without a pool thermometer to check the temperature! Pool thermometers are the most accurate way of determining when your pool water is warm enough for swimming. In addition, a swimming pool thermometer helps with pool maintenance. Algae and bacteria grow faster in warmer water, meaning you’ll have to add more chlorine and water balancers. A floating pool thermometer is a convenient and inexpensive pool accessory that is durable, shatter resistant and easy to read. And they don’t have to be lacking in style! There are fun pool thermometers that look like turtles, whales, fish and other creatures. Browse our selection now and get ready for swim season!
