cause of the algae in your pool! c.s.
Algae
When a pool turns green, the cause is the build up of algae. To remove the algae, chemicals will need to be bought to restore the PH levels in the pool, killing the algae.
No, but it could cause similar appearing skin irritations.
Use an algaecide and test for phosphates.
Yes, a pool can get orange algae.
Red or pink algae in a swimming pool is actually a bacteria. The most common cause is contamination from swimming suits when going from the ocean to the pool. Chlorine is the most effective treatment. Algae products will not work because it is not a true algae.
Iodine contamination - don't ask how it could happen. Very high levels of CYA - cyanuric acid or conditioner.
I expect that the pool has a history of algae growth. Algae often forms itself in a circle, eating away the gunite underneath it.
I am not sure why this has not been answered. The most common reason for the green is algae growth. If you put on a solar cover and ignore pool maintenance, then the algae will grow as the water heats and when you remove the cover, the pool will be green
If it is genuine 'black algae' it is very difficult to remove without emptying the pool and gouging the black algae out of the pool surface. Other algae can be removed by shocking the pool, filtering continuously and brushing walls while maintaining a good sanitizer level.
well when you leave your pool covered for the winter, you are unable to put chlorine into it. Chlorine prevents algae so to answer your question, the lack of chlorine causes algae
