Algae in a pool can be unsightly. After all, who wants to jump into a slimy green pool?


But you may want to do more than just scooping it out of your pool and hoping that it won’t come back. Because if you don’t detect and fix the underlying causes, you will find that algae growth can be very persistent.


Don’t know if your pool has a mild or serious case of algae growth? Want to know how to effectively deal with the situation? How can you prevent algae from growing in your pool in the first place? Find out in this post.

How Do You Know If Your Pool Has Algae?


Algae are easily identifiable. They appear as green, yellow or even black slimy stuff that starts to grow on the pool wall and floor. As well as around the water line of your pool or hidden areas.


Why Does Your Pool Have Algae?


The presence of algae usually signals an imbalance of water quality as well as low chlorine levels. Many assume that high chlorine levels will prevent algae from growing but this is not always true.

Algae can also grow when water quality is not right.


Furthermore, you may also see algae growing in your pool because of a faulty filter. A faulty filter cannot do its job properly, and this will lead to a lot of debris accumulating in the pool.


Therefore, if there is a damaged filter, one of the first steps is to replace the filter before embarking on other steps.

How Can You Prevent Algae In Your Pool?


The water chemistry of your pool needs to be balanced (i.e., not too acidic or alkaline). This is the first step to eliminating algae growth in a pool. The chlorine level of the water needs to be checked regularly as well. It should not be below the minimal threshold or algae will grow.


You can prevent algae regrowth (after a pool shock treatment) by turning on the pool pump for 24 hours to ensure continuous water flow. The filters must also be flushed before they are full to ensure that the pumps can push the water through effectively.


What To Do If You Have Algae In Your Pool


Once algae takes hold in a pool (and if there is high proliferation), there is a need to shock the pool by increasing the chlorine levels significantly. It is not enough to use a normal dose of chlorine to kill the algae.


Because of the higher chlorine levels necessary for a pool shock, it is not recommended to swim in the pool for a few days.


After a pool shock, algae need to be removed either by using a net or vacuum to drain them off to the filters or outside the pool system. The more stubborn algae can be removed by scrubbing them off with brushes.


Conclusion


Because algae growth can result from a few different causes, you may want to get professional consultation to determine what is the best course of action to remove the algae.


If you have really stubborn algae in your pool that you can’t seem to get rid of, give us a call!
