Tips for Buying Algaecide
It is not easy to choose the best product for your pool or spa as there are dozens of options on the market. Therefore, you need to consider the following things when choosing one:
Color of Algae
First, you should note the color of the algae in your swimming pool. Different brands are made to treat different types of algae. Match the color of the algae in your pool with the right brand.
If your swimming pool has pink or red color algae, it means that it’s infected with bacteria. Find an algaecide that will kill the bacteria and remove them from your pool.
Pool Friendly Algaecide
You need to make sure that the brand you buy is friendly to your pool or spa. Here, check the product’s label to see if it states that it is pool friendly.

Always look for the stain removing spec when buying your algaecide. There are products that add stains to your pool when you use them. So, avoid them.
The other thing that you should consider is whether the product is foaming or non-foaming. Try to use non-foaming brands since you can use your pool immediately.
We all like to take a dive into water that is clear. Therefore, you should go for a product that cleans your pool and makes it clear. There are a lot of brands that provide this feature.
It is not a guarantee that you will get the best algaecide because it is expensive. Look out for reviews, brand value, and features before you pick one.
