Causes of algae in swimming pools

There are the following reasons why your swimming pool is covered with algae:

• Regular cleaning: You need to understand each cleaning step to ensure the best efficiency, limiting the environment for mold to grow.
• Unsafe water supply: In fact, the water supply is mostly well water. You should carefully research the quality of the well water you use and analyze the substances contained in it to make an appropriate decision
• Ineffective water filtration system: Ineffective circulating water filtration system leads to unclean water and is also the cause of widespread algae growth, difficult to control.
• Sunlight: Open-air swimming pools without roofs allow aquatic plants to absorb sunlight and convert it into energy, growing vigorously.
• Swimming pools have many gaps and cracks: For many reasons, swimming pools have many gaps and cracks that are difficult to clean, which are also favorable conditions for these aquatic species to easily develop.

What types of algae are in swimming pools?

• Blue-green algae: This algae tends to stick to the walls of swimming pools where the light is low, making the surface slippery and causing a green tint to the pool water.
• Yellow algae (mustard algae): Yellow algae are also commonly found at the bottom of swimming pools and on the walls of pools where the water is less flexible. Yellow algae have smaller spores that can easily pass through the filter, so if not treated properly, the algae will grow back many times.
• Black algae: This type of algae is difficult to completely eradicate. The easily recognizable sign is black dots on the tank walls or bottom; spores take root, stick to the surface and multiply into many protective layers, making it difficult to remove.

Tools and chemicals used to treat algae in swimming pools 

• Pool cleaning kit: hose, suction table, pool water test kit, aluminum bar, circulating filter system, pool floor cleaning cart.
• Chemicals to adjust pH in swimming pools: 32-35% HCL acid, Soda chemical, alum for flocculation or PAC flocculant.
