Can cocci grow as a bloom in a pond?

Yes, cocci, which are spherical-shaped bacteria, can grow in a pond environment if conditions are favorable. These bacteria can multiply rapidly, especially in nutrient-rich waters, leading to blooms. Such blooms can impact the pond's ecosystem by affecting oxygen levels and the health of aquatic life. However, it's important to distinguish between harmful algal blooms and bacterial blooms, as their effects and management strategies differ.
