How to get rid of water mold in swimming pool

People of all ages can have a lot of fun and enjoyment at swimming pools. However, if they are not kept up with, they can develop into a haven for a number of undesirable contaminants, such as water mold. We’ll give you a thorough explanation of how to remove water mold from swimming pools in this article, enabling you to keep your pool sanitary and swimmable.

What is Water Mold and How Does it Grow in Swimming Pools?

Let’s start by defining water mold and learning how it develops in swimming pools. Water mold is a type of microorganism that thrives in moist environments and is also referred to as slime mold or pool mold. It manifests as a slimy, greenish-black film on the water’s surface or on the pool’s walls and floor.

The development of water mold in swimming pools can be caused by a number of factors. Water mold can thrive in conditions with poor water circulation, unbalanced pH and chlorine levels, and the presence of organic material like leaves and dirt. The development of water mold can also occur if pool equipment, such as filters and skimmers, is not routinely cleaned and maintained.

How to Prevent Water Mold in Swimming Pools

Preventing water mold from ever growing is the best way to handle it. Here are some pointers to keep pool water mold at bay:

  • Keep the proper balance of water: Maintaining the proper pH and chlorine levels in your pool’s water is crucial. The ideal pH range is between 7.2 and 7.8, and the ideal chlorine range is between 1 and 3 ppm (parts per million). Water mold can flourish in the right conditions if the pH or chlorine levels are too low or high.
  • Clean up the pool: The accumulation of organic matter that can result in the growth of water mold can be avoided by routinely cleaning the pool, including the walls and floor. Make sure to clean the skimmer baskets and filters, as well as any leaves or other debris that may have amassed in the pool.
  • Keep your pool maintained properly: It’s essential to adhere to the manufacturer’s suggested pool maintenance methods to keep your pool clean and in good condition. This may entail performing routine water tests, cleaning the pool’s machinery, and adding chemicals to the water.

How to Detect Water Mold in Swimming Pools

It’s critical to identify water mold as soon as you suspect it exists in your pool. The following symptoms indicate water mold in your pool:

  • Watch for visual cues: Water mold frequently manifests as a slimy, greenish-black film on the water’s surface or on the pool’s walls and floor. It might be water mold if you notice any areas that appear slimy or have a dark, greenish hue.
  • Examine the water: To find out if your pool has water mold, you can also use a pool water test kit. These kits are widely accessible online and at stores that sell pool supplies. To test the water and look for any indications of water mold, follow the instructions on the kit’s instructions.

How to Get Rid of Water Mold in Swimming Pools

If water mold has been found in your pool, it’s critical to take action right away to get rid of it. Here are some methods for eliminating pool water mold:

  • Chemical processes: The water mold in swimming pools can be eliminated using a variety of chemicals. These include algaecides, chlorine, and bromine. When using these chemicals, make sure to follow the manufacturer’s instructions carefully because some of them can be harsh and may necessitate draining and refilling the pool. To eliminate any remaining water mold, it’s also a good idea to shock the pool, which involves adding a lot of chlorine to the water.
  • Non-chemical procedures: There are several non-chemical ways to get rid of water mold in your pool if you’d rather take a more organic approach. The affected areas can be scrubbed with a pool brush before being thoroughly rinsed with a hose. To get rid of the water mold, you can also use a high-pressure water blaster or a pool vacuum.

It’s important to keep in mind that although these non-chemical techniques might be kinder to the pool and its accessories, they might not be as successful at eliminating the water mold as chemical remedies.


Swimming pool water mold can be a bothersome issue, but with the right prevention and treatment methods, you can keep your pool clean and free of this unwelcome contaminant. You can stop water mold from growing in your pool by keeping the right water balance, cleaning the pool and its accessories frequently, and adhering to the right pool maintenance procedures.

Be sure to act quickly to get rid of any water mold if you do spot any symptoms. You can maintain the safety and fun of swimming in your pool by keeping it clean and in good condition.
