- Killing Algae
Without a doubt, this is the main benefit worth noting. Algaecides are made to destroy algae. In this way, you can keep and maintain your pool clean and sanitized. Typically, an algaecide comprises of a powdered or a liquid substance, and it is made to chemically eliminate algae. And the best part is that it does that fast.
Although you might use chlorine in order to sanitize your pool, algaecides do the best job at killing algae. Beware that regular pool vacuums will likely do not do the trick. We recommend you still check out our reviews on the top above ground pool vacuum cleaners because you simply have to have one in your arsenal albeit for other purposes.
- Preventing the Regrowth of Algae
Many pool owners struggle with algae. Even if they do manage to get rid of them, in many instances, the algae will return. This has to do with the fact that an outdoor pool is exposed to elements such as wind and rain. But even when there’s no rain, your pool might still end up infested with nasty algae.
This is why you should focus on maintaining your pool accordingly. And using algaecide might help you in this respect. Not to mention that using such a product requires little time, yet the results are noteworthy.
However, simply using algaecide won’t prevent the regrowth of algae. Many people expect this and end up being disappointed by the product they purchased. You should also ensure that the filter to your pool is clean. In addition, it should work well so that the water circulates accordingly.
- Enjoy a Clean, Sanitized Pool

What Are the Main Drawbacks of Using Algaecide?
Although algaecides can be very efficient in your fight against algae, there are still some drawbacks you should get acquainted with. The thing is that, in some cases, you will most likely need to resort to chlorine to solve the problem.
That’s because, in some situations, chlorine is more efficient in this respect. That is mainly because chlorine oxidizes bacteria and single-celled algae. Basically, this means that chlorine trades electrons.
This is why it is crucial to maintain the right chemistry in your pool. It’s also highly recommended to test your pool water on a regular basis. This is actually the key to maintaining it clean and sanitized.
In addition to that, some algaecides contain copper. In some cases, the copper might end up staining your pool. But this usually depends on the area in which you live. If you live in an area where the water has a high metal content, then using algaecide might result in increasing oxidation.
However, before purchasing such items, you should find a provider that offers a good variety of pool supplies and accessories. High-quality and reliability are aspects you should look for each time you want to make such a purchase.
How to Clean a Green Pool
Having a green pool is a nightmare. This is something most pool owners will agree on. But what makes a pool green? Why does this happen?
For the most part, algae are to blame. Algae grow due to the existence of a chemical imbalance. When you treat your pool accordingly with chlorine, this should prevent the growth of algae. This is primarily why you should aim at maintaining balanced chemistry.
Essentially, if your pool is green, this means one thing: there is insufficient or no chlorine whatsoever in your pool. If you plan to shock the pool, this means that you should be adding a lot of chlorine. Doing a test beforehand is important.
You should also test for pH: if the pH is too high, the shock will make your pool cloudy. And you don’t want that either.
- Are Algaecides Efficient for Cleaning a Green Pool?
This is a good question. And the answer is positive. Depending on the type of product you’ve purchased, some might be more efficient than others. But the truth is that some products are highly efficient.
Algaecides can transform green pools in clean pools right away. It might be a good idea to add chlorine as well. These two combined should help you solve your problem for good. In case your pool is still green after using algaecide, you should add chlorine – that if you haven’t done it before.
Other important steps you should follow are properly brushing and filtering your pool. After shocking your pool, you should notice a significant difference. But the water will most likely still be cloudy.
In order to address this issue, you should focus on brushing. This is usually because, in some areas, the algae might be more stubborn. Now, if your pool is still green after following these steps, then you might be dealing with an imbalance. This is why you should have a test kit.
Types of Algaecides
We’ve already established that algaecides can assist you in killing and preventing pool algae. They are used basically to eliminate small and solo blooms, thus controlling the development and regrowth of algae. But different algaecides work differently, as you might expect.
Quat pool algaecides
Also referred to as Quaternary Ammonium compounds, these usually include detergents. This is why if you add more than the amount recommended by the manufacturer, you will most likely notice foaming.
Basically, this type of algaecides encompasses microbial disinfectants. They attach to the negatively charged component of the algae. In this way, the outer cover of the algae is destroyed. This will enable the chlorine to penetrate and kill it. Usually, the concentration level ranges from 10 to 50.
Polymer pool algaecides
Polymer pool algaecides represent poly-quat elements, and they feature long carbon chains. Similar to the first type of algaecides, they also have a positive charge. This is why they get attached to the negatively charged algae. This is how they manage to smoothen the cells.
In terms of effectiveness, they are considered to be more effective than quat pool algaecides. Their effects are also long-lasting. But usually, they are more expensive, by comparison. As for the concentration of the formula, it ranges from 30 to 60 percent.
Metallic pool algaecides
The third category is represented by metallic pool algaecides, and they incorporate copper ions in their composition. You might be surprised to learn that copper ions have been used for centuries in treating water.
They work similarly to the first two categories. Usually, these algaecides are highly efficient against green and black algae, and their concentration level is 7 percent.
Features to Look for
As opposed to purchasing the first algaecides you find on the Internet, you should compare different options first. This is why we’ve assembled the features to look for before making a purchase. Here they are:
- The color of the algae
Different algae interact differently with specific chemicals and compounds. This is why you should consider the type of algae you’re dealing with before picking a product. Otherwise, you might end up being disappointed that the product didn’t work as you expected.
- Existence of bacteria
In some cases, you might have traces of bacteria in your pool. You should be able to establish this by carrying out a test. But usually, when the algae are pink or red, this might be an indicator that bacteria are ever-present in your pool.
In this situation, you will need a particular type of algaecide if you want it to work as expected.
- Quick action
Even though you might not need to use your pool right after treating it, you still don’t want to wait around for days until you can use it. This is why you should pick a product that is highly efficient and will do its job fast. Getting acquainted with the chlorine chemistry will be greatly beneficial to you.
- Pool friendly
Since there are different types of algaecides on the market, you should be 100 percent sure that you’re purchasing something that’s designated for pools. That would mean that the product is safe to use in a swimming environment.
There are some products that keep your pool clean even during the winter when it’s not in use. There’s nothing worse than opening your pool and realizing that it has become green during the colder season.
- Stain removing
There are some products that could lead to pool staining. This can be very unpleasant. So, make sure you consider the chemical structure of the water in your area beforehand, as this plays a key part in the process.
What are some important maintenance tips that will keep your pool sanitized and clean? Just as with any other thing, maintenance is an important aspect, although it is highly overlooked.
The truth is that, even if the environment is perfect, if you don’t pay attention to maintaining your pool, sooner or later, you’ll find it overflowing with algae. These are some habits that will make the world of a difference over the course of time:
- First of all, you should have a clean filter. The filter should function accordingly, as it has a crucial part in circulating the water. The water must circulate in order for the chemicals to be evenly distributed.
- Every now and then, you should conduct a thorough scrubbing of the pool walls, floors, and steps. Although this is not the most pleasant step, is it necessary.
- Test the water on a regular basis. Afterward, you should ensure that the chemicals inside it are appropriately balanced.
When it comes to differentiating between different types of algaecides, you have to think of several aspects. For one thing, you should think of the type of algaecide you intend to purchase. It is just as important to determine whether the product will cause staining or not.
You should check for a warning on the package, as most manufacturers indicate if there’s an issue in this respect. Copper-based metallic algaecides are known to stain the most. Also, some products offer protection for an extended timeframe, while others have to be reapplied sooner.
- Always follow the instructions provided on the label, especially when it comes to dosage instructions. These can differ depending on the product.
- You should avoid adding algaecide and pool shock in the water simultaneously. Before adding algaecide, you should wait for the chlorine level to be lower than 5 ppm.
- Focus on maintaining balanced pool water: you should steer clear of high alkalinity, pH, or calcium hardness levels.
- Make sure you don’t overdose; always match the dosage to the size of your pool.
- Clean the pool regularly: the presence of heavy organic metal in the pool (lawn debris and leaves) will impair the effectiveness of the algaecide.
- Ensure that the circulation and filtration system works appropriately.
As soon as you notice algae in your pool, you should take the necessary steps to prevent them from taking over the water. In order to solve the issue right away, looking for the best algaecide for pools is a good starting point. Since it is difficult to choose one product out of so many available options, our algaecide for pools reviews should be helpful.
However, make sure you always consider your needs prior to making a purchase. Determine what type of algae you’re dealing with, whether your pool water is balanced or not, and if it needs a shock or not. It’s always a good idea to implement good maintenance practices. This is ultimately the key to enjoying crystal clear water.
