Best Pool Algaecides

Algae Blooms are one of those inevitable parts of owning a swimming pool.

Algae come with a host of problems such as water bugs, infections, and irritants that can damage or pool and are unhealthy to you.

This article looks at some of the best available Algaecides for your swimming pool that works on various Algaes.


When Should You Add Algaecide to Your Pool

A good Algaecide will kill the Algae and mold affecting your pool water; however, it is better to use it as a preventative measure than a cure.

While and Algaecide will not affect your pool water’s pH balance, it will prevent all types of algae from growing. As well as work along with your Chlorine sanitizer to keep the levels balanced.
It would be best if you used your Algaecide after every shock treatment so that it has a better chance to help your Chlorine work for the pH levels to return to normal.

Adding the Algaecide to different places around your pool after shock treatment while the pump is still running is the best time, as this allows the Algaecide to circulate more efficiently.

Ensure to wait 24 hours after the shock treatment when Chlorine was added for levels to slowly return to normal before adding the Algaecide to not interfere with the chemical processes.

Your pool will be safe enough to use 30 minutes after using Algaecide, as most Algaecides ate not harmful to you directly.

However, if not used properly, Algaecides such as Copper Algaecide can cause staining to the walls of your swimming pool, and quat Algaecides may foam and damage your pool filters.


Types of Pool Algaes

But Before we can get into which Algaecides to use, let us first take a peek at the different types of Algae that may occur inside your swimming Pool;

  • Black Algae – Black Algae usually occurs because someone swam in a natural pool of water such as a lake, river, dam, or the ocean and did not wash themselves or their swimwear before jumping into the swimming pool.
  • Green Algae – The most common Algae we all know is the Green Algae. This is usually because of a lack of sanitation in the pool, inadequate cleaning or maintenance, and a high ph level. So you will most likely notice Green Algae when you have not cleaned out your swimming pool for quite a while.
  • Yellow Algae (Mustard Algae) – The Yellow or Mustard Algae is predominant in Souther areas because of the climate and is basically a form of Green Algae that is resistant to Chlorine.

Things such as a change in water temperature or high water temperatures, sunlight, improper pH balance, and a faulty filtration system are all causes of Algae forming inside your swimming pool. If you address some of these issues and regularly maintain your swimming pool, you should most likely not have Algae issues.

  • Sodium Bromide – Sodium Bromide us the best choice as a sanitizer and Algae inhibitor that kills Algae and bacteria, as well as works in conjunction with Chlorine.
  • Silver Algaecide – Silver Algaecide effectively kills BLACK ALGAE, which is notoriously hard to get rid of. You can also use this Algaecide in conjunction with other products.
  • Copper Algaecide – Copper Algaecide is one of the most common types of Algaecides and usually the cheapest. Algae hate copper. That is why it is so effective.
