What causes green algae in hot tubs?

There are many various causes of green algae in your hot tub. The most common cause of green algae in your hot tub is due to imbalances in the water. These imbalances can occur due to fluctuating levels of pH or from not having enough sanitation chemicals. 

Sanitation chemicals include brome and chlorine, and having the proper amounts of these chemicals can ensure a safe and clean hot tub. If your tub is experiencing any of these imbalances, then green algae will appear.
