Is Pool Algae Harmful To Humans?

Logically, a pool that has algae should not be swum in because just the sight of the green color the algae gives the water should scare you.

However, if you swim in a pool affected by algae, you will not be affected unless you have a little cut or wound or the water gets into your nose, mouth, and ears. The bacteria found in the algae can infect your wound or cut, cause skin rashes and reactions, and make it difficult to breathe, especially for asthmatic patients.

Can you get sick swimming in a green pool?

A pool can get green due to the presence of algae and some metals like copper and iron. Although algae are not totally harmful to the human body system, it is the bacteria that affect you.

If your immune system cannot fight these bacteria when it gets into your body through a small cut, wound, or nose or any other opening in the body, it may result in different ailments such as infection, rashes, sore throat, redness of the skin, and other breathing difficulties.

When you see a green pool, no matter how desperate you want to swim, first get rid of the algae or test to know why the pool is green.

How can algae in a pool hurt you?

Algal growth on the walls and floor of a pool makes it slippery and invites other bacteria and organisms to bloom in the pool.

As a result of these slippery effects the algae gives the pool, you might fall when climbing the steps or touching the walls of the pool or drown as a beginner. And it also introduces bacteria to your skin, making it prone to rashes and other reactions.

Can you swim in a pool with algae?

Swimming can be done as an exercise to calm your nerves and muscles. The sight of algae in pool water should scare you from even entering the pool,

However, swimming in a pool with algae is not totally bad, because algae has no effect on the human body. What should disturb you is the bacteria that feeds on algae.

If they get into any opening in your body, it can lead to infections, reactions, and different ailments. In summary, you should not even consider swimming in a pool that has algae blooming all over it.

How do I get rid of algae in my pool fast?

When you start seeing algae growing in the pool, then the presence of phosphate and nitrate is confirmed because these algae feed on phosphate for growth.

The best and fastest thing to do to stop algae is either reduce the phosphate level or add chlorine to sanitize the pool, but it is preferable to do both.

You can also use an algaecide in the pool and a clarifier to improve the clarity of the pool.

Is algaecide harmful to humans?

Algicide is one of those chemicals that should be left for some hours in the pool before jumping in and swimming.

For health and safety reasons, algaecide should be allowed 5 to 6 hours in the pool to fully take effect before swimming. Algaecide contains strong chemicals which should not get in contact with the body, especially the eyes. They could lead to redness and swollen eyes. In other words, after applying the algaecide, filter, aerate, and backwash the pool before swimming.

How do I keep algae free in my pool?

Different factors make algae get into your pool; it could get in from your water source, if you have trees around your pool, or if you have not considered washing the pool thoroughly.

Although it might be present in small amounts in the water and you cannot see it, algae feed on phosphates. So, you will need to reduce the level of phosphates in the pool to reduce the rate of algae growth, but this does not kill the algae.

So, to eliminate the algae, after applying your phosphate to the pool, you would want to make sure that you brush and shock or apply chlorine to the pool to sanitize the pool and kill the algae.

Phosphates in a pool should not be higher than 200 ppm while the chlorine level should not be lower or higher than 1 to 4 parts per million, respectively.

Does warm pool water cause algae?

The temperature of water is a very small determinant of whether algae will bloom in your pool or not.

Even though algae survives and grows very fast in a low temperature, it will also do well in a warm temperature, but it does not mean that because your water is warm, algae will start entering the pool.

Warm water does not cause algae, but it can be a good environment for algae to grow in. What causes algae is low chlorine level, presence of algae in the water source, leaves and so many others.

Do leaves in the pool cause algae?

Although algae might be present in small amounts already in the water from your water source and you cannot see them, once the chlorine level of the water drops and phosphate or nitrogen gets high, they start feeding and growing massively and rapidly.

Algae and some trees share a symbiotic relationship. The tree helps the algae to grow as it feeds on it, while the algae provides oxygen for the trees. When the leaves from the trees are blown into the water, you can never tell if algae is already on them. If it was, then the leaves will introduce the algae to the water and if the environment of the water is suitable enough for the algae to do well it will start blooming.

Should you cover a pool with algae?

Covering a pool should be significant when you do not want contaminants like leaves, debris, mica and even insects to get in your pool or you are preparing for the springtime or winter.

Covering a pool that has algae does not really make any sense. Brush the pool, treat the water, and eliminate the algae before you cover it.

Should you cover the pool every night?

When you do not want insects or reptiles to get into your pool, you can cover it before you go to bed at night.

Many pool owners cover their pools at night when they cannot watch the weather conditions especially in springtime or rainfall, so that they will not have to start treating and testing the pool all over again in the morning when it rains at night. If you are not expecting rain because it is not the season, then you can save yourself the stress and leave the pool open.

Should I drain my pool to get rid of algae?

Algaecide should do the perfect work of getting rid of algae, after brushing the pool, just add your algaecide.

But if you feel like you have just enough water and less algaecide, you can drain the pool completely, but you will have to wash, clean and brush the pool thoroughly if not the algae will still stick to the floor or walls of the pool and still affect the next water you will use to fill the pool.

How often should I change swimming pool water?

The type of pool you use or the size of the pool should tell you when to change the pool water.

If you use an inflatable pool, you can change the water every day after swimming or every 2 days depending on if you treat the water.

If you use an above-ground or in-ground pool that is very large, you can change the water every 4 weeks. But if your pool is used commercially, you should change it even more regularly.

Another factor that should make you decide when to change your pool water is the seasons and how you prepare the pool for the season. When you do not cover the pool in preparation for winter, make sure you drain the water completely during summer.

Note that every time you change the water, you should check the pH, chlorine, phosphate, and nitrate levels. And if your pool is not very dirty, you can just go ahead and treat it.
