Swimming Pool Algaecide

Pool algaecides are specialized chemicals designed to prevent or eliminate algae growth and algae blooms in swimming pools, which can cause unsightly green water and pose health hazards for swimmers. They come in various types, including copper-based and quaternary ammonium-based algaecides. Each type has its own unique properties and advantages, but they all work in a similar way: by killing or inhibiting the growth of algae.

Regular use of high-quality algaecides can enhance water clarity, water safety, and improve the overall aesthetic appeal of your pool. At Doheny's, we offer the best algaecides and algaestats tailored to meet the unique needs of your pool, ensuring crystal-clear water all season long. Shop algaecide today and keep your pool algae-free!

What is the best algaecide to buy?

There are so many different types of algaecides for swimming pools out there, it can be difficult to know which one to choose. Well, don't worry, our Doheny’s Pool Pros have done the research for you. We'll break down their recommendations so you can be sure you find the best algaecide for your pool.

Algaecides are chemicals specifically designed to kill existing algae in pools and other water systems. They are typically used as a treatment when algae have already formed and are causing visible issues, such as green, yellow, or black discoloration in the water. Regular use of algaecides can help clear up algae problems, but they are most effective when combined with proper water balance and filtration.

  • Doheny's Super Algaecide Plus: Algae is no match for Super Algaecide Plus from Doheny's! This pool algaecide features a powerful formula of chelated copper that kills all common algae growth: stubborn green, black algae, and even kills persistent yellow mustard algae. Our brand of algaecide will not foam or cloud your swimming pool water.
  • Doheny's Total Algaecide: A true algae killer, this extra strength pool algaecide destroys all types of stubborn algae- including black, mustard, pink, and green. No algae is safe with this effective swimming pool algaecide! Total Algaecide for swimming pools is a non-foaming, non-staining formula which also significantly clarifies pool water. Be proactive in keeping your swimming pool crystal clear. Total pool algaecide will prevent new algae growth for a full 90 days.

Algaestats or algae preventers, on the other hand, are chemicals that work to prevent algae growth rather than eliminate it. They disrupt algae's ability to thrive, making them a key part of a proactive pool maintenance routine. By using algaestats regularly, pool owners can reduce the likelihood of algae outbreaks and minimize the costly need for stronger algaecide treatments.

  • Doheny's Algaecide 60: Effective against all types of algae and safe for your pool fixtures, Doheny's Algaecide 60 is our most popular and highest-concentrated pool algaecide preventer.

Our products eliminate existing algae and provide long-lasting protection to keep your pool water crystal clear. With our specially formulated algaecides, you can enjoy peace of mind knowing you have a reliable solution at your fingertips.

Frequently Asked Questions about Pool Algaecide

Q. How much pool algaecide do I use to clear algae?

A. As a general guideline, most pool algaecides will require adding around 2-4 fluid ounces of the product per 10,000 gallons of pool water. However, it is important to note that this is a general guideline and the specific dosage may vary depending on the product being used and the severity of the algae problem. Always follow any additional instructions provided by the manufacturer, such as waiting a certain amount of time before swimming or adjusting the pool's pH level.

Q. How much pool algaecide to use weekly to help prevent algae?

A. The amount of algaecide for pools to add on a weekly basis can vary depending on several factors, such as the type of algaecide being used, the size of the pool, and the frequency of pool use. As a general guideline, many pool algaecides recommend adding around 1 fluid ounce per 10,000 gallons of pool water on a weekly basis to help prevent algae growth.

Q. How do I get rid of algaecide foam in my pool?

A. If you have added pool algaecide to your water and notice foaming or bubbling, there are a few steps you can take to get rid of the foam:

  • Turn off the pool pump and filter system to allow the foam to settle.
  • Skim off any excess foam from the surface of the water using a pool skimmer.
  • If the foam persists, you can use a pool defoamer product, which is designed to break up foam and prevent it from reforming. Follow the manufacturer's instructions for dosage and application.
  • Turn on the pool pump and filter system and allow it to run for several hours to help circulate the water and distribute the defoamer product.
  • Monitor the pool water and repeat the process if necessary.
  • Excessive foaming can be a sign of an underlying issue, such as high levels of organic matter or an unbalanced pH level. Regular maintenance and monitoring of pool chemistry levels can help prevent foaming.

Q. Do I add algaecide before or after shock?

A. It is best practice to first shock the pool before adding algaecide. After shocking your pool, it is generally recommended to wait at least 24 hours before adding pool algaecide. This allows time for the shock treatment to dissipate and the chlorine levels in the pool to stabilize. Adding algaecide immediately after shocking the pool may reduce the effectiveness of both the shock treatment and the pool algaecide.

Watch Now: Helpful Tips On Getting Rid of Pool Algae

  • Before you can effectively treat algae in your pool, you need to know what type of algae you're dealing with. There are three main types of pool algae: green, yellow, and black. Green algae is the most common and easiest to treat, while yellow and black algae are more stubborn and require stronger pool algaecides.
  • Pool algaecides come with specific instructions on how to use them. Make sure to read the label carefully and follow the instructions to the letter. Using too much algaecide can be harmful to swimmers, while using too little may not be effective in eliminating algae.
  • The best time to add pool algaecide is in the evening after the sun has gone down. This will give the algaecide time to work overnight without being broken down by the sun's UV rays. Make sure to turn off your pool pump and filter before adding the pool algaecide to allow it to settle to the bottom of the pool. 
  • To help the pool algaecide work more effectively, brush the walls and floor of your pool to loosen any algae that may be clinging to them. Then, vacuum the pool to remove any debris and dead algae that may have accumulated.
  • Proper pool chemistry is crucial in preventing algae growth. Make sure to regularly test and balance your pool's pH, alkalinity, and chlorine levels to keep them within the recommended range.
