Keeping a swimming pool clean is an essential part of enjoying it.

What is Algae?

Algae are aquatic plants that are commonly found in stagnant or still waters like ponds, lakes, and swimming pools. It is microscopic and appears green, yellow, or brown. When it grows on pool surfaces or filters, it can be unsightly, slippery, and unsafe.

There are many types of algae that can grow in pools, and they come in different shapes, sizes, and colors. Some of the most common types are:

1. Green Algae: This is the most common type of algae found in pools. It makes the water look green and slimy.

2. Yellow Algae: Also known as mustard algae, it appears as yellow or greenish-brown spots on pool surfaces and is quite challenging to eradicate.

3. Black Algae: This type of algae is dense and black, and it is difficult to remove once it has taken hold.

4. Pink Algae: Pink algae isn't actually algae but a type of bacteria. It usually grows in areas with low circulation like corners, stairs, and other shaded spots.

Now that you know what algae is and the different types, it's time to get rid of it from your pool filters. Here's what you need to do:
