Algae are present in polishing ponds and water storage ponds for supply and, in excess, can cause eutrophication in the receiving body and odor and taste in the water. Some genera of the Cyanophyta division produce cyanotoxins, promoting a toxic effect on the system's biota.

Due to the environmental importance of the algae bloom phenomenon in ponds and tanks, Genetica Bioscience offers a quick and conclusive microscopic analysis for taking action.

Ecological consequences of excessive algal blooms in rivers, lakes, reservoirs and estuaries:

• Increase in particulate organic matter (BOD)
• Increase in organic substances that can impart flavor and odor to the water
• Excessive increase in pH
• Excess sedimented algae causes anaerobiosis, releasing hydrogen sulfide (toxic), ammonia, iron, manganese, phosphorus, etc. Anaerobiosis may also occur in the water source where the effluent is released, causing the death of aquatic fauna

Below are the main characteristics of each algae division.
