If you realize your pool water is turning green, the first thing that might come to your mind is dirt in the water. The look is unpleasant, and the water may be unsafe. Pool algae can be due to various causes. That means cleaning the pool and draining the dirty water may not be the ultimate solution.
Knowing what causes pool algae and the best ways to get rid of it permanently is crucial. The following are details of types of algae, their causes, and how to eliminate the problem.
Types of Pool Algae
Identifying these different algae will help you know how to remove them. The main thing that differentiates these types is their colour.
Green Algae: Green algae are common among types of algae in most pools and it is easy to recognize and kill. However, green algae can spread quickly, hence the need to remove it before it clouds the entire pool.
Black Algae: Black algae are mostly found in poorly maintained pools. The issue with this kind is that it is hard to kill because it has a protective layer on top and can penetrate deeply into hard places. Therefore, you must remove it even with the slightest sign.
Yellow Algae: Also known as mustard algae, yellow algae are rare, mostly found in humid places. It does not spread quickly, but it is hard to eliminate.
Pink Algae: Pink algae are uncommon but appear as reddish slime along the water line. It is easy to remove and kill.
Causes and Remedies for Pool Algae
Algae is the main reason why your pool water is green. While it is normal to see algae growth in ponds and streams, an overgrowth in a swimming pool can cause health risks. That is why it is advisable to apply basic pool maintenance to eliminate the issue. The presence of algae means there is an imbalance in the water that requires fixing. Here are the causes and solutions for pool algae.
pH Too High and Low Chlorine Levels
One major reason for algae overgrowth is high pH levels. The pH level of the pool water should be balanced between 7.3 and 7.6. If the level is too high, it hinders the chlorine. The work of chlorine is to purify the water and kill all harmful organisms. Therefore, ensure the chemical levels are balanced, and chlorine level is normal.
Pollen and Metal Elements
Pollen and other metal elements can also contribute to the green or cloudy colour of the pool. Metals react with chemicals in the water, causing an imbalance. This imbalance may encourage algae growth. It is advisable to call a professional to check the pool. Make sure you also vacuum the pool and brush its floor and walls.
Dirty Filter
The work of the filter in the pool is to trap debris and other elements from the water. That is why the filter is always dirty and green when you remove it. Hence, if the water is dirty or green, the issue could be coming from the filter. It could be worn out, or you are not running it enough to filter the dirt. So, deep clean filter cartridges or replace the entire filter and ensure it is also running for at least eight hours a day.
To Sum It Up
These are the main causes and solutions to pool algae. To eliminate the issue, you should take your time to understand why it occurs and learn to maintain the pool chemistry. A healthy pool means you can freely enjoy yourself at any time and avoid the risks that come with harmful bacteria from the existence of pool algae.
