How to Choose the Right Algaecide?

There are so many algaecides, and it is essential to choose the right one for your situation. There are different types of algae, including red, green, and yellow. Many algaecides can easily kill green algae. But for black algae, you need a specific mix to get rid of it.

If you use the wrong one, it is highly unlikely that you will be able to get rid of all the types of algae. Four primary algaecides are commonly used, out of which quats are the most common algaecide.

Quats contains quaternary ammonium salts that cause your pool to foam. This is very effective for the pool. They are also available in three concentrations, including 5%, 10%, and 30%. This is also an excellent algal inhibitor.

If you do not want the algaecide to foam your pool, then you might want to go with one that has a polymer additive, making them poly quats. It is the best suited as it does not foam and can fit in your weekly pool cleaning routine.

Apart from this, if you want to kill specific forms of algae, such as pink, mustard, and black, then you can choose specific forms that include silver, copper, and magnesium to see the effectiveness. There are algaecides as algae stats. While algaecides kill algae, algae stats prevent its growth.

What Causes Pool Algae?

If you own a pool, then you have to understand how algae are caused. This will not only help you treat algal growth but also prevent any future growth. It can be caused due to various factors, including poor water sanitation, poor water circulation, and water balance.

Water Temperature

Algae prefer warm water. Higher temperatures are the main cause of algal growth. It also contributes to nitrogen, which causes algae to thrive. This can cause algal bloom.

Sunlight

Sunlight helps in preparing chlorophyll in plants. This pigment causes it to grow. Algae, just like plants, contain this pigment. When you have an outdoor pool, sunlight can aggravate algal growth.

Filtration System

If your waterbody is not connected to a proper filtration system that aids in aerating the water, it will cause algae to bloom. This is why pools need to have a good filtration system. For a pool to be healthy, it should have a filtration system that will at least filter water for six to eight hours.

Fertilizers

Along with your pool, if you own a garden and would use plant fertilizers to keep them green and clean, you need to take proper measures to keep them away. Just like how these fertilizers will give plants nutrition to grow, they will help algal growth.

How to Prevent Algae Growth in Pools?

Algal growth is common but can be prevented with the right steps. Here are a few steps that can save you a lot of money, effort, and time.

Good Circulation System

A circulation system will keep water and other chemicals flowing throughout the pool. If your pool system has a good and well-maintained circulation system, then algal growth will hardly occur.

Proper Sanitization

Your pool can have spores brought in, causing algal bloom. This is uncontrollable as the wind brings this in. Chlorine usually kills this, but just in case, if it doesn’t, then algae might end up growing.

In order to prevent the chlorine level from changing, it is better to use a chlorinator. This is why it is important to sanitize your pool regularly.

Maintain a Routine

Many algaecides work better if you brush the walls, floors, and the steps of your pool. Algae grow easily in these areas, and brushing them can prevent them from developing roots. If you maintain a routine and brush these places weekly, you can prevent algae.

You can find the right brush to scrub your pool effectively. You can either buy brushes made of vinyl-lined, fiberglass, acrylic, or even nylon. It is better to use brushes that are softer to prevent the surface from cracking open.

Endnotes

To sum it up, there are so many different algaecides. If you have a pool, you need to ask all the right questions before you finalize one. Algaecides do the work, but before that, you should develop a proper routine to keep your pool away from any sort of algae to save you any trouble.
