How can you choose the best types of swimming pool algaecides for your facility? Follow these buying guide:
- Types of Algaecides
The different kinds of swimming pools algaecides you can find include:
- Quat Pool Algaecides – Short for Quaternary Ammonium, Quat algaecide disinfect pools by washing the algae. They are detergents that cause staining, odor, and foaming when added in excess.
- Polymer Pool Algaecides – Also known as Poly-Quat, the Polymer Algaecides suffocated algae growth and are 2x faster than Quat. They do not stain or foam your facility.
- Metallic Pool Algaecides – They are useful in yellow and black algae, just like Silver algaecides. These products are robust, expensive, and can cause staining on hair and walls because they contain copper.
- Sodium Bromide – It is not an algaecide, but it kills and prevents algae from developing in your swimming pool. You can add this product and then the United Chemical No Mor Problems Algaecide to avoid the onset of algae.
- Types of Algae
Some products only treat yellow or mustard algae, others treat black algae, and others treat green algae.
Others are designed to kill and prevent all types of algae.
It is an algaecide whose effect is felt for a few months, like 3-6 months. Some products kill and prevent nuisance for only a few hours.
- Color of Algae
Always match the color of the pool algae with the right algaecide. Different brands of algaecides produce products for treating various types of organisms.
- Top Performer

Your pool is infected with bacteria if it has red or pink color algae. Go for a product that will remove or kill the bacteria.

- Pool Friendly Algaecide
Always ensure you buy a product that is friendly to your swimming pool. Pools come in different types like vinyl, concrete, granite, and others.

- Clarifying Brand
Who does not like to swim in crystal clear pool water? Hence, choose an algaecide that cleans and makes the facility clear.
- Age of Algae
It takes time to treat older algae. A standard polymer or even a metallic-based model works fine for fewer server cases.
Use the sodium bromide-based products to treat the stubborn algae and then add an inhibitor like No Mor Problems.
- The Price
The price is another thing you should consider when buying the best algaecide for your pool. Most of the products are cost-efficient and last for months before the need to replenish them.
We would recommend you buy the model you can afford and one suited for the types of algae in your pool.
What is the Strongest Algaecide?
The most potent algaecide can easily remove yellow or mustard algae and often contains sodium bromide.
Most of the copper-based products will work for other types of organisms.
The most potent algaecide should be the one that removes all the organism in your facility and make it crystal clear.
Can I Put Shock and Algaecide in the Pool at the Same Time?
Shocking and adding pool algaecide is an effective process for removing algae from the swimming pool.
However, you should not shock and add the algaecide at the same time because they become ineffective when they mix.
That means algaecide and chlorine become useless when they come together and will not kill or prevent pool algae.
You should shock your pool and then add the algaecide when the chlorine level gets to 5 PPM.
When Should I Add Algaecide to My Pool?
It is the best way to kill all tiny algae spores the processes might have missed. Pool algaecide also helps to prevent the regeneration of the organisms.
However, there are other times you should consider using your pool algaecide:
- You can add these pool and spa products before you close or shut down the facility for winter.
- The algaecides should also be sued when opening in summer or spring.
- It is also advisable to add the pool algaecide to prevent algae growth.
- Some pool owners add the pool and spa algaecide on sunny days – pool algae love the sun.
- Other people treat their swimming pools with algaecide weekly as part of pool maintenance.
Professional Tip: Add the pool algaecide when the sun is out to get the best results. The organisms grow when the sun is out.
What is the Best Chemical to Kill Algae in a Pool?
Many brands use copper-based ingredients to produce algaecides. They either contain copper chelates or copper sulfate, which are chemical compounds.
The two coppers contain metal as their primary central atom. Some manufacturers use sodium carbonate peroxyhydrate or herbicide endothall instead.
All these chemicals work by disrupting the algae’s cellular processes by cutting energy cells and preventing cell divisions. Some avoid the fusion of new protein cells, which are vital for survival.
You might also see the product you purchase containing different concentrations of active ingredients. Some of the chemicals include polyquaternium WSCP, copper pentahydrate, and sodium bromide.
They are all-powerful chemicals for treating different types of pool algae.
Professional Tip: You might risk oxidating your pool and staining the walls if you add high quantities of these chemicals. Copper can significantly damage your pool if you leave in areas with water with a high level of metals – use a copper-free product.
Keeping pool spa green algae, yellow algae, blue-green algae, and black algae can be a daily battle. But you can win it with the best pool algaecide.
Adding these swimming pool chemicals during pool maintenance is probably the best way to handle the nuisance.
