Types of Pool Algaecide 

Due to the different kinds of algae, there are different types of products you can you to kill and prevent them. They are often classified as follows:

Quat Pool Algaecides 

Quat or Quaternary Ammonium compounds are detergents that remove most kinds of algae in a swimming pool. They work like how a dish soap removes grease on your pan.

That means they attach to the algae cells and dissolve their membrane to allow the chlorine to get into the contaminant. Quat algaecides are quite economical and come in 10% or 50% concentrations. 

Sadly, if you add a lot of them, they might lead to foaming because they are soap. On the north side is that they don’t stain your pool. 

Polyquat/Polymer Pool Algaecides 

These are quite vibrant and come with two main selling points over other types of algaecides. They are non-staining and non-foaming.

They work like the Quat models by attaching to the negatively charged cells of algae, spreading to the bloom to ensure that the contaminants don’t grow. These products last two times longer than Quat models, but they are more expensive. 

They come in 30% or 60% concentrations.

Metallic Pool Algaecides 

They use positively charged metal ions to attach the outer cell of algae, poisoning the nucleus of every cell to prevent an infestation. The bad thing about these products is that they can cause staining if you over-use them. 

You should use metallic products if your pool in infested by black algae. 

Sodium Bromide 

Sodium bromide is not classified as an algaecide, but it works wonder when killing and preventing algae growth. It works with your pool chlorine to remove algae and ensure they don’t get into your pool any time soon.

Its reaction can quickly reduce the level of free chlorine in your swimming pool.

Quat algaecides are cost-effective, but they can easily mess your swimming pool by creating foams. Polymer models do not stain your facilities or create foam, but they are more expensive.

Metallic algaecides are the most effective of all the three types, but they can easily stain your pool due to their copper element. 

We would recommend you use the polyquat models like the ones we have reviewed above.
