Fighting Against Pink Algae In Your Pool
What is Pink Algae?
This is more of a bacterium than algae, but is found in corners and crevices of the pool. They form in spots and, thankfully, do not spread easily. They are not known to spread over the entire pool and bloom.
How can you kill Pink Algae?
The best option, like many others, is to shock the pool and brush the walls. After, be sure to vacuum and backwash the filter. Once this is all done, make sure that all the chemicals in the water are balanced and that the water gets good circulation. If the algae keeps coming back, then an option might be to drain the water and clean the walls with an acid to another material. However, be aware that the liner, if there is one, might need to be replaced if it is ruined upon refilling the water.
