How to Remove Algae from Pool

Algae can impact any swimming pool and quickly spread if you don’t act fast. I make take more than killing algae with standard chlorine, as you will need to perform a few steps additional steps to take care of this problem. There are three different types of algae that affect swimming pools: green, yellow, and black algae.

Green is the most common type of algae, and it’s the easiest to remove. Yellow algae are rarer, as it’s often misidentified as sand or pollen in shaded areas of your pool. Black algae are the most difficult to remove, as they can put roots in pool surface and quickly spread.

Following a few steps can help you remove algae from your swimming pool.

Check Your Water Balance

One of the first methods in getting rid of algae from your swimming pool is to check your water balance levels with a kit. The recommended pH level needs to be between 7.2-7.6 for optimal results. You will need to continue to modify the chemicals in your pool until you reach this range.

Clean the Filter

The next step in removing algae is to clean the filter. You will most likely have algae growing in your filter if it’s already in your swimming pool. Typically, you can clean your filter by washing down the cartridge, or you may need to backwash a sand filter, both using a professional grade filter cleaning solution. The cleaning methods will vary depending on the filter.

Brush the Pool

After you are finished cleaning the filter, you will need to use a pool brush for cleaning all of the steps, walls, and floor. Thoroughly brushing all of these areas is especially important if you are dealing with black algae. Chemicals can’t always break through black algae, as scrubbing these areas is essential before spreading to more places.

Shock the Pool

Shocking the pool with calcium hypochlorite dichloro or trichloro (only for white plaster pools) granular  is the next step in removing algae. Following the instructions from the manufacturer is essential in using the right balance. It’s recommended to shock your swimming pool at dusk or night, as the sun will prematurely burn off the shock during the day.

Always choosing to wear protective gloves and eyewear is vital while handling any chemicals.

Test Your Water and Add Algaecide

Afterward, you will need to check the water to balance the chlorine and pH levels. If the chlorine level is still too low, you may need to repeat the shocking process for another day or two. You will have to wait until the next morning before adding algaecide. You will need to follow instructions from the manufacturer to help you determine how much to use for the size of your pool. Do not overdose!

Brush Your Pool Again

You will need to wait another 24 hours after using algaecide before brushing your pool again. You will brush the same areas, including the steps, walls, and floor of the swimming pool. It’s critical to vigorously brush all surfaces to avoid algae appearing again in the same locations.

Vacuum Your Pool and Continually Run the Filter

Once you are finished brushing, you will need to vacuum the pool to remove any remaining dead algae particles and loose debris. The skimmer also plays an important role in removing any leaves and debris on the surface. Turn the filter on and let it operate non-stop until the water is clear.
