How to Eliminate Pink Algae in Pool

Pink Algae in Pool

It’s important to understand that pink algae isn’t algae; it’s a type of bacteria. This bacteria is present in all water bodies and occurs naturally. The pink hue comes from pigments in its cells. Pink algae thrive in pools with limited sunlight exposure, low water movement, and minimal sunlight. It’s also commonly found in PVC material used in pool construction.

What Is Pink Algae?

Pink slime is a kind of bacteria that looks like reddish-pink gunk. It can leave slimy streaks on light fixtures, in the small spaces and corners of your pool. You might also see pink algae on the water’s surface, slowly spreading across the pool.

Why Does Pink Algae Happen?

Finding pink algae in your swimming pool indicates that you may not be taking good care of it or that the water isn’t getting enough sunlight. Rainwater getting into the pool could also contribute to its growth. Even if you’re regularly maintaining and treating the pool with chemicals, pink algae can still thrive. It’s tough, resisting both chlorine and bromine. Even after treatment, it can stick around on pool toys, skimmer buckets, garden hoses, and fountains.

Why Do I Have Pink Algae Infestation in My Pool?

The pink algae on your pool’s surface looks like a slimy, pink or clear layer. You’ll usually find this pink layer in parts of your swimming pool where the water doesn’t move much and where there’s direct sunlight. There isn’t one specific reason for pink algae, but it often happens because of poor pool maintenance and water chemistry that lets bacteria and algae grow.

Is Pink Algae Dangerous?

Pink algae might not look great, and it can make pool gear slippery. But don’t worry, it’s not harmful to your health because it’s not a germ. Remember, you should never drink pool water, whether there’s pink algae or not. It’s crucial to remove pink algae to keep your pool safe. It can harm your pool plaster and equipment if left unchecked.

How Can I Keep Pink Algae From Growing in My Swimming Pool?

You can manage pink algae by taking preventive measures. Keeping your pool’s chemicals balanced is key to stopping its growth. Regularly brushing and vacuuming your pool, plus covering it when it rains, can help reduce pink algae. Sunlight’s UV rays are natural fighters against it, so it’s essential to uncover your pool on sunny days, even if you’re not using it. Regular cleaning and shocking your pool can also prevent pink algae.

How to Remove Pink Slime From the Pool

Many pool owners ask, “How can I get rid of pink algae in my pool?” We’ll look at both chemical and natural methods to remove pink slime.

Chemical Methods

1. Balance Chemicals

To prevent bacteria and algae from growing, it’s important to keep your pool’s chemicals balanced. Ensure the pH, water hardness, and alkalinity are at the correct levels. The pH should be between 7.2 and 7.8, calcium hardness between 200-400ppm, and alkalinity between 100-150ppm.

2. Shock Treatment

The most common way to get rid of pink algae in a pool is to shock it with a lot of chlorine. This kills the algae and stops it from coming back. To shock your pool, you need to increase the chlorine level to 12 ppm. 

Make sure to follow the instructions from the product you’re using and wait until the chlorine levels drop back to normal. When the chlorine level is between 1.0 and 3.0 ppm, it’s safe to swim again.

3. Algaecides

Algaecide is another choice. It’s a chemical made to fight algae in swimming pools. While algaecides work well against pink algae, it’s important to remember that pink slime is actually caused by bacteria, not algae. 

However, some types of algaecides can kill this bacteria. You can find these treatments at local pool stores.

Natural Methods

1. Brushing

Removing pink algae from your pool surfaces can also be done by hand-brushing. It might take a while, but if you keep at it regularly, it can really work well.

Brush the pool’s sides, steps, and bottom to lift up the pink algae. Once you’ve brushed everywhere, run the pool filter non-stop. You should also backwash the pool twice a day until the water looks clear again.

Keep brushing the walls and vacuuming the pool bottom. Doing this, along with filtering and backwashing, will get rid of any leftover algae.

A cleaning mitt is a handy tool for scrubbing algae off areas around skimmers and other spots like stairs, ladders, and returns without harming the pool liner. This latex glove lets you scrub safely.

2. Proper Water Circulation

Pink algae like to grow in water that doesn’t move much. To stop this, make sure your pool water keeps moving by running the filter and pool pump for longer times.

Getting rid of any algae takes time. Pink slime is tough and can resist many chemicals.

If pink algae aren’t completely gone, they might keep growing. A big outbreak can make the water look cloudy or even turn green.

If that happens, you might be facing a bigger issue, like stains in your pool.
