9 Ways to Prevent Algae Growth in Your Pool  

What is the color of your pool water? If you find the pool turns green, brown, black or yellow, it is mainly because of the algae growth. We can find algae more or less in every pool, but if it can resist the normal chlorine level in the water, it starts spreading at a higher rate. You have to consider the following things to prepare algae pool treatment– 

  • Check the chlorine and phosphates levels in the water.
  • Temperature of water
  • Dirt in the water

Why Did My Solar Pool Cover Turn My Pool Green? 

If you already have low chlorine and phosphate levels in the pool water, a solar pool cover helps in algae growth. The main reason is that the solar cover maintains a warm temperature which is favorable for algae to thrive in the water. 

The solar cover does not turn your pool green; it actually warms the water up to 5 degrees, which accelerates the algae growth. 

That is why I always suggest not keeping your pool cover on for more than one month because it makes the restoration process harder. If you have done it, take the water sample and check the quality of the water. Only an expert can access the water and suggest the best way of pool water conditioning.  

Black, Browne, Yellow Algae Pool Removal

If you want to do it yourself, then here is a DIY solution, but I would not recommend it because only an expert understands the condition of the water. 

  • You have to use an algae starver that balances phosphate in the water to reduce algae growth. 
  • Empty the pool water and refill it after two days. It helps to remove the algae spores in the pool. 
  • You have to use a pool cleaner to ensure there are no algae spots inside the filter and pool.  
  • If the situation is difficult, you should consult with an expert. 

Professionals will assist the pool water and restore the chemical balance for the next exciting pool session.  

Ways to Prevent Pool Algae Growth in Winter 

Note: Though it prefers warm water, it also grows in the winter months. How can you reduce it? Follow these steps to keep your cool water warm and fresh. 

Take Prevention 

Clean the pool regularly, especially before pool sessions. Check the chemical balance and give it the necessary treatment it demands. You can also apply an algaecide as a preventive measure.  

Keep Cover on 

Keeping a solar pool cover on also prevents algae growth because it prevents outside dirt from entering the pool. Besides that, it also prevents bacteria and debris from decomposing in the water. Keeping out debris and sunlight are the main preventive measures for algae growth.

Check the Cover 

You use a cover that does not mean you do not clean the pool or cover. That is why you can schedule an expert visit or do it yourself to keep the surrounding and full cover clean for a long time. However, you should not cover your pool for more than a month. In that case, you can uncover a pool for 24 hours and then filter the water and cover it again. 

Consult with an Expert  

If you are out of your house for a few months, you have to cover the pool, and after that, schedule an expert visit that gives you the best remedy to restore the chemical balance in the water. 

Chemical Balance 

Algae growth happens due to chemical imbalance in the water. Sometimes the chlorine level drops a little, which leaves the door open for bacteria such as algae. That is why you have to keep the pH between 7.2 and 7.6. I understand it is tough to understand this technical jargon; please consult with a local expert for more details. 

Give It a Treatment 

Generally, experts advise at least one chlorine shock treatment in a month if the water is between 50-70 degrees Fahrenheit. If the water is more than 70 degrees Fahrenheit, you need that treatment once every two weeks. 

Keep the Filter on 

A stagnant pool creates an environment for algae growth. That is why you have to switch on the filter once a week to run the water. It would be better if you did it yourself. The filter consumes energy, so if you want to save energy, you can do it once a week. 

Maintain the Appropriate Temperature 

You have to maintain a temperature that is not suitable for algae growth. I understand that it is tough if you are too busy on weekdays. However, it is more suitable for a pool owner. Indeed, you can schedule an appointment with an expert to check the temperature of the water and get better guidance. 

Use Pool Cleaner 

An automatic solar pool cleaner is a wonderful way to manage pools. You can buy a pool cleaner and run it once a week to keep your pool clean, preventing algae growth.
