Pool

Typical sanitizer levels are no match for pool algae. On a sunny day, algae photosynthesize and multiply rapidly, growing your little problem into a pool-sized one in no time.

It’s easy to ignore a little cloudiness or some stubborn, dark debris by your stairs, especially when your pool is getting heavy use. However, overlook algae for just a little too long, and you’ll wind up spending a lot of time and money to get rid of it.

Before that slimy nuisance grows out of control, get rid of algae in your pool with a unique deep cleaning procedure. Then make sure it never comes back by using smart prevention measures like our eco-friendly pool cleaning solutions.

Pool Algae Symptoms

  • Even if you don’t have lily pads floating on your pool’s surface, you could still have a plant problem. Algae get into your water in many ways, such as microscopic particles on someone’s swimsuit or a little patch of slime on a pool float.
  • However it’s introduced, you’ll want to get rid of it as quickly as possible. If you fail to maintain balanced water chemistry, you might as well formally invite your algae to make itself at home in your pool and stay forever.
  • Unlike the harmful algae blooms found in marine waters, none of the three types of pool algae are detrimental to swimmers. Your algae cloudiness could be so thick that you wouldn’t be able to see a struggling swimmer underwater. They also provide food for some types of bacteria you don’t want in your pool. Plus, slime-filled pool water is just uninviting.
  • Algae’s most noticeable symptom is discolored pool water. Depending on the type of algae infecting your pool, the water may be greenish, yellowish, or even blue-black. Gross, right?
  • Another telltale sign is residue in any of those colors around stairs, in corners, on pool walls, and around jets and skimmers. Algae love to grow in nooks and crannies where you may not see it until it’s too late.

Pool Algae Types

The exact tint of your water might not be so distinct, plus it’ll be cloudy, so it may be difficult to tell which kind of algae has taken up residence in your pool.

To be sure which type of algae is in your pool—which will determine how you get rid of it—take a close look at any spots where algae are starting to grow.

  • Green algae
    • The most common and most natural algae problem to kill is Chlorophyta, which gets its color from chlorophyll. Green algae float in the water, making it cloudy and giving it a greenish tinge. Slimy green algae also attach itself to your pool walls and floor. Poor filtration and lack of proper sanitization boost green algae growth. It can be introduced to your pool by algae exposed swimwear and toys.
  • Yellow algae
    • If you see what looks like pollen or sand in a shady corner of your pool, you probably have yellow algae. It’s also sometimes called brown or mustard algae. It’s rare, and not slimy like green algae. It’s also chlorine-resistant, which makes it tough to treat, whatever name you call it—even the four-letter names.
  • Black algae
    • Technically a cyanobacteria—not algae at all—this nasty offender makes its food, so it grows and grows. Not only that, its roots dig into concrete surfaces, making it tough to kill black algae. It’ll grow back quickly if your treatment isn’t aggressive enough to ensure none of the roots hang around.

Pink slime is another bacteria that grows in pools, especially inside polyvinyl chloride (PVC) pipes. It’s sometimes called pink algae, but that’s a misnomer. You can get rid of pink slime in your pool, but it’ll take some hard work. You can at least rest assured that pink slime isn’t harmful to humans. We can’t say the same for your pool, however.
