If you have lived in Polk County for more than one summer, you already know the drill. It is two o’clock on a scorching July afternoon, the sky turns a menacing shade of purple, and within ten minutes, a classic Florida downpour is dumping inches of rain into your backyard pool.

Living in Central Florida comes with plenty of sunshine but it also means dealing with afternoon thunderstorms, tropical weather and weeks of heavy rain.

One of the biggest misconceptions I hear from homeowners is: "The water looks great, so everything must be fine."

Your pool doesn't usually go from perfect to green overnight. In most cases, it gives you little warning signs along the way. The trick is knowing what those signs are trying to tell you.
