DIY or Contacting a Professional

There are two ways to deal with black spot algae in your pool: you can either do it yourself or you can hire a professional. There are a few things you should know if you decide to clean it yourself.

First, you need to identify the type of algae you’re dealing with. There are many different types of algae, and some are more difficult to treat than others. Once you’ve identified the type of algae, you need to find the right treatment. Not all treatments will work for every type of algae.

Algae can be killed with chlorine, so adding more chlorine to your pool is the first step. However, you need to make sure that the chlorine levels are right or you could end up damaging your pool.

If you decide to hire a professional, they will probably add chlorine to your pool and then shock it. This will help kill the algae. If the algae are in a difficult spot to reach, they may use a pool brush or an automatic scrubber to remove it. You should ask them what they are going to do before you hire them so that you know what to expect.
