What are the two main nutrients that cause algal and other undesirable aquatic growth?
Answer:
Phosphate, and Nitrate.
the water temp and the sun,they explain it in an episode of dirty jobs maybe you can see it if you go to discovery channel.com
are you located next to any agricultural enterprises? if so, runoff from the fields may be getting into your pond, lake, etc. causing the algae to have excessive bloom.
It depends on bacteria and the environment that feeds the bacteria which could be aerobic or anaerobic. Before you can deal with the growth and I would assume you want to eliminate it, you have to find its food source and eliminate that. Are you inquiring about a koi pond?
Warm temperatures and nutrient levels cause algae blooms. The levels of phosphorous and nitrogen and lack of water turbulence may result in blue-green algae multiplying quickly.
Exposure to some blooms can pose risks to humans, pets, livestock and wildlife because of the toxins present. Exposure may occur by ingestion, skin contact, and aspiration or inhalation.
In addition, when the bloom dies off, decomposition can result in reduced oxygen levels and fish die-offs.
