The presence of pink slime in your pool tells you one thing: that you’re not doing enough upkeeping of your pool.
Pink slimes are actually algae with pink pigments. Scientifically, they are a type of bacteria known as Methylobacterium. Although it’s non-pathogenic, meaning it doesn’t cause diseases, it doesn’t mean that it’s okay to have them in your pool.
The pink algae population can grow exponentially when not removed early on. Their presence can dilute the effectiveness of chlorine and bromine – the chemicals that kill harmful microorganisms in pool water. This means that a high concentration of pink algae promotes the breeding of harmful bacteria, potentially putting your health at risk.
Plus, pink slime makes the surface slippery, which can lead to an accident. With all these concerns, it’s best to get rid once and for all.
How to Get Rid of Pink Algae
Looking for effective ways to remove these pesky algae? Here are some steps that you can take:
- Scrape the pink algae from the surface using a pool brush. Brush all surfaces of the pool, even those with no sign of pink algae yet.
- Turn the pool filter on and backwash the pool until the water becomes clear again.
- Continue brushing the surfaces and backwashing to thoroughly flush out the pink slime.
- Fill the water with fresh, clean water. Run an automatic pool cleaner first to ensure that the water is thoroughly clean.
- Balance the chemicals. The correct level of alkalinity, pH, and water hardness is crucial in preventing pink slime development. Test the pool water for these standards and adjust when necessary: alkalinity: 100-150, pH: 7.2-7.8, and calcium hardness, 200-400 ppm.
The steps above might take you days to finish. Here is a pool cleaning timelapse to show you the amazing result.
If you clean the pool for pink algae, make sure you do it right the first time. Pink algae have the characteristic of being resistant to many cleaning and sanitizing processes. If they are not entirely removed, there is a big chance that the problem will recur.
Many brands of algaecides are available in your local pool store that are specifically formulated to kill pink algae. The most common method of using them is to mix a quantity on the dirty pool water while brushing the surface.
