When water is stagnant, has a high temperature or a high concentration of Nitrates and Phosphates, an algae bloom might occur, which can cause several problems. Blue-green algae growth, also known as cyanobacteria, can cause a foul odour to the water, a layer of scum on the surface and even pose a health risk. Green algae may colour the water green, look unclear and plants can die. Therefore an algae problem is often unwanted and algae control is desired.
