Keeping Georgia’s Pools Sparkling Clean Since 1981

A Guide to Different Types of Pool Algae

There are many joys that come with having a pool. They’re fun for kids and grandkids, offer privacy that a public pool can’t, and are the perfect place for some relaxation in the sun. Although there are many perks, taking care of a pool is no fun. Being informed about how to care for your pool properly will help keep it in tip-top shape so that the fun can carry on. Utilizing pool cleaning services in Duluth helps take the burden off of you and your family. One thing that can really wreak havoc on a pool is algae. There are many different kinds, and knowing how they form and how to get rid of them is very helpful. Algae are classified by colors.


Yellow alga is the mildest form because it has the slowest growth rate. However, it still can be difficult to remove, and pool cleaning should be done immediately after noticing there’s been a bloom. The surface layer is removable with a brush, which will leave the underlayers exposed and in need of chemical treatment. This treatment is best performed by a professional using something called superchlorination to get rid of the yellow algae at the source.


Not surprisingly, green algae are the most common algae that grow in swimming pools. To stop it in its tracks, you first will want to apply a chemical treatment, followed by a thorough swimming pool cleaning. This alga starts out as a green slime on the surface, but if it’s not caught early on, it will grow really fast and can take over your entire swimming pool before you know it. Even though Shrek’s swamp wasn’t half bad, you don’t want your backyard pool to start to resemble it! Once you find green algae, you’ll want to be very diligent about cleaning to ensure it doesn’t come back. The longer green alga grows, the harder it is to get rid of it.


Black alga just sounds terrible, doesn’t it? It’s so much the opposite of your beautiful, shiny, clean, crystal blue pool. It’s the most dangerous of the three algae and first appears as little black specks, kind of resembling dirt on the bottom of your pool. Possibly the only good thing about this black monster is that it does grow at a slower pace than the other two algae. But, be careful, because once it starts to grow larger, it grows at a very quick pace. Catching this form of algae early on actually makes it rather easy to remove. However, if not, you may have a huge mess on your hands. This alga can get so bad that it may cause you to have to remove your entire pool. It differs from yellow and green algae because it can survive in less light and at a greater depth, which makes it easy to form on the plaster and grow deep into the concrete of your pool. If you start to see a little “dirt” on the bottom of your pool, get some professional pool services to take care of it immediately.

Having good swimming pool care in Duluth makes all the difference in enjoying your summertime backyard pool. Not only will it save you the work of cleaning, but it will also give you peace of mind that you’re swimming in clean and algae-free waters!
