The presence of algae in your pool is a clear sign that something is wrong, and you need to ensure that your pool is correctly maintained to remove it and prevent it from returning. In fact, there are a few things you can implement to keep your water looking great and prevent the build-up of algae.  When preventive measures are not enough, it is essential to first remove algae from your pool before using it again.

Here are the different types of algae and how to remove them:

  • Green algae

his is the most common type of algae and the most opportunistic since it often infests swimming pools that are not properly sanitised. In fact, green algae can frequently appear overnight following heavy rainstorms. The reason for this is that rainstorms can provide nitrogen which is considered the food for green algae.

The best way to treat green algae is to prevent it from infesting your pool in the first place. You can use a chemical called algaecide as part of your typical maintenance program. This will help prevent the build-up of algae by eliminating the existing algae and preventing renewed growth. However, you will need to maintain circulation during treatment.

  • Mustard algae

Mustard or yellow algae is similar in form to green algae, but it grows slowly and can easily be identified since it infests both pool walls and floors. Since mustard algae grows very slowly, it is also challenging to treat. In fact, by the time you see it in your pool, it may have been there as long as three weeks. In addition, this type of algae loves to grow in dark areas of your pool and can affect the performance and stability of the filters and plumbing system.

The only way to treat yellow algae is to use copper-based algaecides, which are well-suited for this type of algae. Although it is unusual to treat mustard algae since you will need to use the chemical more than once to put it under control. Therefore, prevention is always better than cure.

  • Pink algae

Pink algae will appear as a reddish slime and will usually appear at a pool’s waterline. It will also stick to PVC surfaces, especially in the pool’s piping system. Fortunately, this type of algae is the easiest to maintain and can be removed by simple brushing and regular sanitizing. Although if the build-up of pink algae is out of hand, you will need to shock your pool with a calcium hypochlorite solution.

Overall, if your pool is already infested with algae, it is recommended that you run the pump, an essential pool maintenance feature, more often. Also, keep the water balanced, which means you will be doing a lot of testing. Finally, remove things from your swimming pool, such as inflatable toys, floats, leaves, and grass. Make a real effort to keep your pool clean and algae-free.
