Top four types of Pool Algae

After the algae get into your pool, it flourishes and makes the water dirty. To make matters worse, some algae types are resistant to chlorine bleach, heat, and other soft corner chemicals. Now, let us see the types of algae and their effects on your pool.

Green Algae

Greenish tinge in your pool? Green algae float on pools, making them cloudy and hard to see through. Some side effects of these algae include slimy water, slippery walls, and visual pool quality.

Luckily, green algae are the safest of them all, and you can swim in them. However, if you are allergic to algae, don’t even think of entering the algae-filled pool. A fresh batch of green algae can appear after heavy rain, and they are the safest of them all.

Then again, green algae carry some nasty bacteria that can cause skin infections. So, you can swim in a pool with algae if the water isn’t too filled up with green slim.

Yellow Algae

Yellow algae are rare but can still appear in your pool. They have a yellowish membrane, representing pollen or sand. If you find them in your pool, they often stay in a shady corner of the pool and are resistant to chlorine and other cleaning agents.

Though it’s soft and squishy, the algae aren’t slimy, unlike their green rivals. If you want to eliminate them from the pond, try pumping all the water out and keep the pool dry.

Black Algae

These nasty offenders are direct relatives of the green algae and are extremely hard to kill. You will find their roots concentrated on the surface of the pool. Additionally, they come back even after you drained all the water out.

You can try covering the pool and regularly cleaning the water with a pool pump.

Pink Algae

Pink algae or pink slime is often found in PVC pipes and can sometimes reach your pool. Having a smiley appearance, you will often confuse it with green algae. However, these aren’t algae, and nor are they harmful to humans. So, you can swim through a pink smile without thinking too much.

Hazards of swimming in a pool with algae

Algae contains bacteria, which can kick-start an allergic reaction. Now, let us see the safety risks of having pool algae in the first place.

Physical Injuries

This may not as a surprise, but algae are kinda slippery. You can seriously injure yourself with bumps and bruises. If you are not careful, you can even break a bone by slipping on the mush of algae.

Bacterial infections

Bacterial will find its way to every living thing. Algae is a storehouse of different kinds of zooplankton and, yes, bacteria. Ingesting some bacteria-filled algae can wreak havoc on the body, causing fevers, diarrhoea, and so on.

Sensitive skin issues

People with sensitivity shouldn’t try swimming in algae-filled pools. Doing so can cause some nasty allergic reactions, which can even lead to death. To check whether you are allergic or no, just put some algae on the part of the skin. If the skin turns red, then you are allergic to it.

Cloudy water

If the algae are too much, then it can turn the water cloudy and decrease visibility. Drowning accidents can happen if the water isn’t crystal clear or has algae all over. Cuts and bruises are another risk factor of having a pool with low visibility.

Getting rid of algae from the pool

Are you annoyed by having too many algae in your pool? Well, nothing to fear. Cleaning these pests is easy as pie. All you need is a pool pump and a water filter.

  • Get a sand water filter from the market and make sure the filter is a big one. You may have to clean the water every once in a while.
  • Pump the water out and filter it through the sand filter.
  • If it is possible, find an inflatable pool and place the clean water in it.
  • Try to avoid immediate refilling and wait for the pool to dry off.
  • Now place the water inside the pool after filtering it again.

Is a pool with algae safe to swim in?

Well, the right type of algae can end you in the hospital or some severe skin condition. Some algae can kick-start a severe allergic reaction, and so you need to be careful. Often people with less allergic problems can swim easily on green, yellow, and pink algae.

Are algae in the pool dangerous?

If the growth of algae is too much, the pool isn’t safe. For starters, algae contain bacteria that can give you a fever, diarrhoea, and other nasty diseases. Though you can swim in algae, prevention is better than cure.

Does chlorine kill algae?

Chlorine can help clean out green algae. But when it comes to cleaning yellow or black ones, finding a solution with chlorine is kinda tough. They are resistant to chlorine, and you need to empty the pool to clean them.

At what temperature algae grow in a pool?

Algae are highly adaptive and can last until the water is 65-degree Celsius. Even in freezing climates, algae can survive and grow back when the temperature is just right.

Endnote

From our part, don’t jump in a pool of algae if the concentration is too much. Often algae-filled pools are safe until the level of algae doesn’t make the whole pool green. You should know, ponds have natural ecosystems that filter the water and keep the algae in check.

However, pool algae induce fever, loose motion, and, yes, allergic skin reaction. So, be careful.
