What is Algae?

Algae start as spores, but if the situation is valid, they can grow large enough to turn the pond green in a few days completely. Algae usually form on the surface of swimming pools but can also form inside pool plumbing and equipment. Algae thrive when it lacks pool disinfectants or unsafe pool chemicals. Therefore, proper care of the pond in the warm season is so important.

Your pool water should be sterilized with strong chlorine to kill any remaining algae and prevent it from coming back.
  2. Pink algae, also known as pink slime or pink mold, is the rarest species in its family. These are not algae but rather bacteria that you will find in PVC pipes and sometimes in your swimming pool. Smiling in appearance, it is often confused with green algae.

Best Ways to Remove Algae from Pool without a Vacuum

There will always be algae in your pool, no matter what you do. Knowing how to remove them early will make a big difference.

It’s important to watch when algae growth starts spreading if you live in a sunny area.

Check the sides of your pool or scan the surface for signs of growth. You can use several ways to clean your pool of algae if you notice any.

Clean the pool filter

Your pool filter is responsible for removing most dead, loose algae from your pool. But this device cannot help you if it is clogged. Sandbox filters must be backwashed appropriately, and other filters such as swimming pool filter cartridges must be cleaned before you can begin collecting your pool water.

Carefully follow the manufacturer’s recommendations when cleaning the filter so as not to injure yourself or your filtration unit.

After cleaning, it will automatically filter the sucked algae into the filter system through the pump.

Check pool pump

The pool pump is responsible for circulating the water so that it can pass through the filter. Check your pool pump and make sure it is not clogged. A pool scraper or strainer can be used to clean your pool pump.

Proper pool circulation is not only important for getting rid of algae, but it will also help keep your pool clean of dirt and other deposits in the future.

Scrub with a brush the pool 

This step is very important. Some algae, such as the black species mentioned above, can be difficult to remove from walls. Try brushing your pool walls regularly and thoroughly so you don’t have to take any extra steps later.

Apply a Shock Treatment

Proper shock therapy or an all-purpose algaecide such as calcium hypochlorite pool shock can be beneficial in eliminating stubborn algae or excessive algae blooms.

These multi-purpose algaecides can burn your skin on contact. Follow instructions carefully when adding these products to your pool. Wear gloves and safety goggles when applying shock therapy, and avoid swimming in your pool for several days after applying shock therapy, or it may cause rashes.

You can also use a pool purifier to clean a pool if the pool is green or cloudy.

Test the pool water

Water chemistry is one of the most important things you should look for to keep your pool hygienic. It bears repeating: check those PH levels! Also, ensuring you have enough chlorine is essential in algae prevention.

Remove large debris

Get a pond net and pick up large green debris such as large chunks of algae, leaves, twigs, and anything floating in your pond. These residues can clog your filter pump.

Natural Home Remedies for Removing Algae from Pools
