it kills animals in the water.
An increase in nutrients can cause algae growth and reproduction to increase dramatically into a bloom.
An "algal bloom".
If there is a massive bloom, then the algae may cover the whole of the surface of the water, in which case it can block out sunlight for other plants and creatures living below the surface. Other plants cannot perform photosynthesis, and therefore fish can feed onm the plants, and gradually a whole eco system can be destroyed. On the other hand, fish or animals that eat the algae can thrive, and the whole ecosystem can thrive as a result. It depends on what else is in the pond really
rivers and run- off from farmers fields bring extra nutrients into a lake allow increased growth of algae in the water. The result is a population explosion of algae called an algal bloom
It is called an algal bloom. Algal blooms can be caused by excess nutrients in the water, such as nitrogen and phosphorus, and can result in the water changing color due to the high concentration of algae. Some algal blooms can be harmful to aquatic ecosystems and human health.
Excessive nutrients, such as nitrogen and phosphorus, in water bodies can cause algal blooms to form. These nutrients provide excessive food for algae, promoting their rapid growth and reproduction. This can lead to a sudden increase in algal populations, resulting in a bloom.
It can cause many animals to go extinction
The main ingredient in fertilizers that can cause algae blooms is phosphorus. When excess phosphorus enters bodies of water, it can promote the growth of algae, leading to harmful algal blooms. These blooms can disrupt aquatic ecosystems and deplete oxygen levels in the water, negatively impacting fish and other marine life.
Tricky question: Maybe! Green water ,on the whole, is caused by algae. Algae is a single celled plant and should cause no problem BUT if the water has algae it usually has little or no chlorine. This is where the problem comes in. With no chlorine you may be glowing pathogens (germs, viruses and Bactria). That's where your problem lies.
Algae blocks out light, causing other water plants to die
Algae blooms are mainly cause by pollution in water. For example, fertilizer that pollutes the water like in streams or rivers...etc.There is always some algae on water, When nutrient in the water is available for algae to grow it will simply grow until it runs out of nutrient. These nutrients have often been introduced as a result of farming and drainage practices.
In a word ~ NO. If the algae bloom is that severe maybe a replaster is in order. Sounds like you need to be more diligent on chemistry in the pool along with proper filtration among other things. Sounds like a problem of neglect. Black algae will bore into the plaster unlike green algae. It is very difficult to get rid of especially on rough plaster. You cannot cover over it or paint over it. Oh, the dark blue liner or any liner can and will cover and hide the algae problem but you will still have the algae problem and in fact compound the problem. The algae could bore through the new liner and then where will you be - - right back in the same boat. k
