Having a pool is a great way to beat the heat in the summertime. However, they can be a lot of work to maintain. One important part of pool maintenance is keeping the water clean and algae-free. Algae can make your pool look dirty and uninviting, which can be tough to get rid of. That’s why it’s important to have a good algaecide on hand, so you can quickly and easily kill any algae in your pool.
There are a lot of different algaecides on the market, so how do you know which one is right for you? In this article, we’ll give you a rundown of the best pool algaecides, so you can find the perfect one for keeping your pool clean and clear all season long. Let’s get started.
When Should I Use Algaecide in my Pool?
Algaecide should be used in your pool when you see algae starting to form. They can start to form in your pool for several reasons, including warm weather, high levels of pool use, and low levels of chlorine.
You should immediately add algaecide to the water if you see algae growth in your pool. They will kill the algae and prevent it from spreading.
You should continue to monitor your pool for algae growth and add algaecide as needed. If you have a lot of algae growth, you may need to shock your pool (with a high chlorine level) and then use an algaecide to kill all of the algae.

Features to Consider While Buying Algaecide for Pools
While many algaecides are on the market, not all are created equal. Here are a few things to keep in mind while shopping for an algaecide to ensure you are getting a quality product:
- Active Ingredients: The active ingredient is the part of the algaecide that actually kills algae. Be sure to check the label to see what the active ingredient is and do some research on it to make sure it is effective.
- Concentration: A higher concentration of the active ingredient will be more effective at killing algae, but it will also be more expensive. You’ll need to decide how much you’re willing to spend and how quickly you want the algae gone.
- Lasting Period: Some algaecides only work for a short period, while others can last for months. If you live in an area with a lot of algae, you may want to choose an algaecide that will last longer to save you money in the long run.
- Safety: Algaecides are chemicals, so you’ll want to make sure you choose one that is safe for your family and pets. Ensure that the product you select is designed for use in pools and that it is safe for human skin contact.
- Ease of Use: Some algaecides require special equipment or mixing before they can be added to the pool, while others come in pre-measured packets that can simply be dropped into the water. Consider how easy the algaecide is to use before making your purchase.
How Do I Put Algaecide In My Pool?
Adding algaecide to your pool is a great way to keep it clean and free of algae. Here are a few tips on how to do it:
- Deposit the algaecide in several spots around the pool. This will help ensure that it covers the entire area evenly.
- Use a brush to spread it evenly around the pool. This will help ensure that all areas are covered and that there are no missed spots.
- Run the filter for 24 hours afterward. This will help remove any residual algaecide from the water and keep the pool clean.
- Ensure proper pH levels in the water. Algaecide can lower pH levels, so monitoring them closely and adjusting as needed is important.
- Monitor the chlorine levels closely. Chlorine levels should be kept at a minimum when using algaecide, as it can cause them to rise too high.

How Long Does It Take Algaecide To Work In Your Pool?
It is important to note that algaecide does not work immediately. It can take a few hours to a few days for the algaecide to kill the algae in your pool. The length of time it takes for the algaecide to work will depend on the type of algaecide you use, the severity of the algae problem, and the size of your pool.
If you are using an algaecide for the first time or have a severe algae problem, it is best to wait at least 24 hours before swimming. This will give the algaecide time to work and prevent you from coming into contact with potentially harmful chemicals.
Once the algae are dead, you will need to vacuum your pool to remove the dead algae and debris. You may also need to brush the sides of your pool to remove any stubborn algae growth. After vacuuming and brushing, your pool should be ready for swimming.
Do I Use Shock Or Algaecide First?
If you are starting with a new pool, you should use shock first. This will kill any bacteria that may be present in the water. Once the bacteria is gone, you can then add algaecide to prevent algae from growing.
Can You Put Too Much Algaecide In A Pool?
No, you cannot put too much algaecide in a pool. If you do, it can make the water unsafe to swim in. Always follow the directions on the algaecide package and only use the amount recommended for your pool size.
Should I Run The Filter After Adding Algaecide?
Yes, you should always run the filter after adding algaecide to your pool. This will help circulate the chemicals and evenly distribute them throughout the water.
Will Algaecide Help A Cloudy Pool?
Yes, algaecide can help a cloudy pool. If algae causes cloudiness, the algaecide will kill the algae and clear up the water.
Does Algaecide Make Pool Foamy?
No, algaecide does not make the pool foamy. If your pool is foamy, it is likely due to something else such as soap or detergent getting into the water. Also, look for non-foaming formulas if you are concerned about this.
How Do I Calculate The Amount Of Algaecide Needed For My Pool?
The amount of algaecide needed for your pool will depend on the size of the pool and the level of algae present. Follow the recommended dosage on the package for your pool size. You may need to increase the dosage if you have a lot of algae.
To sum up, the best algaecide for pools is the one that suits your particular needs the best.
