One of the most irritating moments for pool owners is getting ready for a quick dip in the pool on a hot sunny morning only to find out that the water is contaminated and has turned green. Although a green pool isn’t much to be worried about, it looks not only unhygienic but also unappealing, ruining the whole appeal of your backyard.
Why does it happen, even though you remember leaving crystal clear water the preceding day?
Well, the answer is algae. If your water isn’t chlorinated well enough, you can see algae growth all over your pool overnight – especially if you live in a hot area like Arizona! The best way of keeping your pool water clear is by regulating the level of chlorine in it, which can be done quickly by adding chlorine tablets.
However, what to do if your water is already green? Is there no option other than replacing the water?
Fortunately, that’s what we’re here to discuss today; the best green pool algaecides you can find in 2021. Here, you’ll find # of our top picks out there to clean your pool water out, and a user guide to help you get the most out of your purchase.

Buying Guide for the Best Green Pool Algaecides
Now, knowing what type of green pool algaecide is best is one thing; knowing which one suits your needs is entirely another. Here are two primary things you should consider before making a purchase.
Types of Pool Algae
Following are the more common types of Algae;
- Green Algae – Aka the blue-green algae, these are what you find most of the time thriving in your pool.
- Yellow Algae – Aka the yellow-green or mustard algae, these thrive without sunlight and are chlorine resistant most of the time.
- Black Algae – This alga thrives in plaster pools, growing roots through the plaster. These are also chlorine resistant, along with the majority of algaecides.
- Red Algae – Aka pink slime, this is another chlorine resistant algae that thrive in sunlight but can survive without it too. It is more common in colder climates.
How Green Pool Algaecides Work
Algaecides target small, singular blooms in order to prevent algae development or halt it further. Each algaecide functions differently, and here are how some of the common ones perform their function;
- Quat Pool Algaecides – Also known as Quaternary Ammonium compounds, these algaecides are more like detergents. For these, it is important to have circulating water, and their detergent-type nature means overuse can lead to foaming. These algaecides attach to algae, destroying the outermost layer that protects them from chlorine. Once disintegrated, the chlorine can penetrate the algae and get rid of it.
- Polymer Pool Algaecides – These algaecides are poly-quat elements forming long chains of carbon atoms. They don’t foam and are positively charged. As they come in contact with algae’s cover, they neutralize it, letting chlorine do its job properly. These algaecides last much longer than Quat and are therefore more expensive.
- Metallic Pool Algaecides – These are the most expensive algaecides out there, but also the most effective ones. They follow the age-old trick of using copper ions for treating water. These not only clear up the water by bonding with amino acids in the water but also deteriorate the outer cover of algae and letting chlorine do the rest.
If you’ve ever experienced a green pool, you know exactly how much of an annoyance it can be, not to mention the hassle it creates of cleaning up. Algaecides help you tackle this issue, whether you’re simply trying to ensure that your pool remains clear or want to clear the green waters.
We hope one of the above-listed green pool algaecides can help you keep your pool water crystal clear, letting you dive into the cool water on a hot summer dare.
