Factors to Consider When Buying the Best Pool Algaecide
Maintaining your pool isn’t as simple as rushing out to buy one of the algaecides on our list. There are different considerations to keep in mind that’ll help you determine which type of pool algae control your home needs.
What is Algaecide?
Many outside factors contribute to algae growth such as the weather changing or a failed filtration system. It’s vital to add an algaecide pool treatment to your routine pool maintenance so that you’ll have cleaner water to swim in.
Type of Algae
There isn’t just one kind of algae. This living plant organism comes in a number of different colors that help determine its species and normal habitat. The types you’ll typically find in pools are green algae, yellow-brown algae, and black algae.
It may be simpler to find effective pool algae killer for green algae. This type usually forms in your pool after neglect. The free-floating algae winds up clouding up the water, but this is easy to both treat and prevent.
With black algae, you’ll have your work cut out for you. This can form a protective outer layer as it sticks to your pool’s surface, and like yellow-brown algae, it can fight off your filter and chlorine.
When it comes to pool maintenance algaecide, consider finding treatments that don’t cause any staining. You don’t want the treatment to kill the algaecide but damage the rest of your pool.
Also consider how long the active ingredients last. Quality algaecides may last up to six months or so before you need to re-treat your pool again.
Pool Algaecide FAQ
How do pool algaecides work?
Algae are an all-too-common issue, and many turn to algaecides when learning how to get rid of algae in pools. They work along with chlorine to kill any algae cells in the water by causing the cells to burst. When used on a regular basis, the chemical treatment can help block it from forming.
When should I use algaecide?
The best time to add algaecide to pools is on a weekly basis. This may not only help kill the algae in your pool, but also do a better job at preventing it from coming back.
Will I notice results in my pool right away?
The time between adding the algaecide and noticing results vary depending on the algaecide you’re using. Some may show a clear pool in two days, while others may take around five days or so.
Are algaecides safe to use in pools and spas?
High-quality algaecides, when used according to the directions, shouldn’t cause any permanent damage to your pool or anyone swimming in it. You should always search for treatments designed to be safe for your filter as well as feature non-foaming and non-staining ingredients.
Is algaecide the only effective method in getting rid of pool algae?
Algaecide isn’t the only option when searching how to remove algae from pools. You may use chlorine in your water as it can oxidize the bacteria and cause rupture much like algaecide does. Of course, this is only an option for those of you who don’t mind a good of chlorine in your pool.
