Does Warm Pool Water Cause Algae

These conditions include out of balance water, warm temperatures, sunlight and presence of nitrates, phosphates and/or carbon dioxide. A lack of good circulation, filtration and sanitation is usually a contributing or the primary cause of pool algae.

At what temperature does algae grow in a pool?

As I previously mentioned in my list of pool care essentials, having a thermometer to track your pool temperature is important because algae loves to grow in hotter temperatures––generally 85 degrees or above.

Does algae prefer warm or cold water?

Warming water temperature Toxic blue-green algae prefer warmer water. Warmer temperatures prevent water from mixing, allowing algae to grow thicker and faster. Warmer water is easier for small organisms to move through and allows algae to float to the surface faster.
