Sooner or later, regardless of the pool being newly built or not, you’ll come face to face with the algae-problem. When these aquatic plants appear in your pool, you know something went wrong with the water chemistry. Although not as easy to get rid of them as they appear, they can be dealt with in a relatively swift manner if you act fast, preventing their growth and reappearance. In this article, we’ll help you identify what type of alga you’re facing, how to fight and remove it efficiently, as well as the methods through which you can ensure it won’t return to your pool.
Despite the different species variation in nature, the algae that grow in pools are of only five types. You can easily identify them through their color, as well as the color they make the water take. Therefore you can distinguish between green, black, pink, and yellow. Let’s discuss them in detail.
It takes its color from the chlorophyll pigment inside its cells and will take several tones of green, even going into the blue and yellow spectrum. Due to this, it will give the water an intense greenish color, with patches here and there, if it sticks to the walls, or a more blurred tone if it floats freely. Luckily, it contains no toxins that could become a health issue, but it will stick to skin and clothes if you wish to swim in the basin. Although on its own it is harmless, it creates a perfect breeding ground for other types of bacteria, like E.coli, which, in turn, can cause stomach problems.
Although part of the same family as the green one, this type is more resilient and harder to get rid of. It usually takes a powdery yellow hue, like turmeric or mustard, so it’s relatively easy to identify. Due to its aspect, it can be easily mistaken for sand, or simply a spot in the water. Although rarer than green, it is also a tad difficult to get rid of, as it loves to stick to several elements, including pool walls. It also attaches to toys, equipment, brushes, and swimwear, and it has a higher tolerance for chlorine.
Even though its name makes you think of pink seaweed, it is not related to the water-loving plants. It is, in fact, a bacteria that has a slimy armor around it which makes it resilient to external factors. Although rare, it prefers plaster-made surfaces and will attach itself on and inside these elements. Despite its strange color, it is easy to deal with, requiring few actions from your part.
Last but not least, the black menace is a pool owner’s worse nightmare. This type can easily invade all kinds of basins and doesn’t shy away from chlorine. In fact, it is completely unaffected by natural amounts of sanitizers, therefore making it quite a pain to deal with. It loves to glue itself to surfaces with high porosity, sticking its roots deep, to ensure an even harder removal.
Now that you’re familiarized with the different algae types and how they present themselves, you’ll have an easier time distinguishing between them and acting fast against them. Although the overall removing process is relatively the same for all types, for yellow and black it will vary slightly, as these two tend to be a bit more difficult to deal with.
Instead of having to deal with these aquatic pests, it’s better to prevent them from getting into your pool. While many of their spores travel by air or are easily brought in by a wide array of possibilities, you can stop them from taking roots by following a strict cleaning program. A thorough weekly upkeep routine will keep them away and will preserve the clarity of the water.
All in all, depending on what type of algae has appeared in your basin, there are different ways to deal with them. While some can be easily removed, others require a lot more effort from your part. So, the best method to deal with them is to prevent them from taking root in the first place. A good water balance and perfect circulation combined with regular upkeep will help you avoid water bacteria and pathogens.
