Most pool owners have at one time battled with algae in their pool. Algae are living marine creatures that rapidly multiply in warm, sunny weather. Since algae have chlorophyll, they use photosynthesis to flourish. That is, they take in carbon dioxide and release oxygen as a byproduct. Algae spores may get into the pool through rain, wind, or contaminated equipment and swimsuits. When the swimming pool conditions are not well balanced, an algae bloom can occur overnight. These pool conditions include an improper imbalance of water chemicals, presence of nitrates and or carbon dioxide, warm temperatures and sunlight. Of course, poor circulation, filtration and sanitation are always the main cause of the algae. Algae blocks filter pores causing a decrease in the filter effectiveness which may require you to do more backwashing. It consumes chlorine in the water that should be used on other contaminants creating a higher chlorine demand in the water. Algae itself does not harm swimmers but if a pool has algae, it may be a haven for pathogens like E-coli bacteria. Although algae do not harm swimmers, no one wants to go swimming in a pool that is full of algae.

How To Get Rid Of Algae In Pool
Once you realize your swimming pool has algae, you have to find ways of how to get rid of it. There are several ways you can use to solve you algae dilemma. Proper identification of the type of algae growing in your pool is very important for effective treatment. But before you begin the treatment process, use a good pool brush to scrub off the algae from the floor and the sides of your pool to break it up so that the chemicals can work faster. If your pool is made of concrete, use a steel brush but if it is a vinyl pool, a nylon swimming pool brush is recommended. Here are some methods you could use to get rid of algae nuisance in your swimming pool.
Shock Your Pool With Chlorine
To completely get rid of all the algae in your swimming pool, you need to double shock your pool even if it’s just a light shade of algae. Below is the recommended a guideline for double shock treatment to your pool.
Pounds of Shock
|2||10,000 or less|
If your pool has a lot of algae, you will need to triple the shock. Sometimes your pool water may turn black green due to excess amounts of algae. To clear this “creature from the black lagoon” you will have to quadruple shock your pool. It is important to blend the granular chemical with a little water in a basin so that the chemicals can quickly dissolve before you shock your swimming pool. Water should never be poured to a chemical, instead, always pour chemicals to water. After blending the chemical with some water, gently pour the mixture into the swimming pool so that all the water in the bucket is evenly distributed in the pool and that it doesn’t just settle at the bottom of your pool. You can use your filtration system to assist in mixing, accelerating the process of oxidation and distribution of the shock treatment in the pool. If your pool has not made any change for the better, you can always add another dose of shock. Repeat this process until your pool condition improves.
Use Of Algaecide To Treat Algae In The Pool
This is a very easy and quick method of removing algae from your swimming pool. Algaecide is a chemical treatment for fish ponds, swimming pools and other aquatic bodies that kills algae. Algaecide comes in two forms: quaternary ammonia and metallic which is made of silver and copper. Although both types are very effective, ammonia is the most commonly used because it does not stain your swimming pool and it’s cheaper than the metallic algaecide. However, the quaternary ammonia tends to foam up which most people find irritating.
Some types of algae cannot also be eliminated by the ammonia algaecide especially the black algae. If your pool has this kind of algae, get an algaecide specifically made to eliminate this tough kind of algae. The active ingredient (ammonia or metal) for the algaecide you choose should be at least 30 percent. If it is less than 30 percent, it may not effectively kill all the algae in the swimming pool. After adding the algaecide in your pool, let it stay for at least a day before you do anything to the pool.
Using algaecide regularly in your swimming pool also has other benefits. It prolongs the lifespan of your pool filtration system since there are less plant materials that block the filter and intakes of the swimming pool pump. It also reduces chlorine use for purification of pool water therefore your swimming pool water becomes more pleasant to swim in and effects of eye sores due chemicals are drastically reduced. You should also note that the algaecide used for killing bacteria may be different from the one that is used in preventive maintenance of algae. For the chemical to be effective, all the manufactures instructions should be followed effectively.
Using Both Algaecide And Shock Treatment Methods
This is one of the most effective ways of eliminating algae from your swimming pool. Make sure you first use algaecide then you shock your swimming pool otherwise you may not get the desired results. After the algae are dead, you then vacuum them out of your swimming pool. Dead algae are very easy to clean out since they become very soft and fluffy. If you are using your filter to vacuum, it should be set to waste. Make sure you properly clean your pool filters so that all the algae is cleared out of the pool. If the filters are not completely cleared out, the algae may start to bloom again. Lastly, test your pool chemical levels using home test strips to ensure they are correct for your swimming pool.
Take Action Now! Stop Algae In Your Pool
The right chemical and sanitizer balances helps in preventing any opportunities for algae growth. High pH and low levels of chlorine create a good environment for multiplication of algae. Maintaining a general cleanliness of the pool is also very important in the prevention of algae growth. This can be done by occasionally brushing off your swimming pool even though it may seem clean on the sides and the bottom. It will also help preventing cloudy pool water.
If you keep your pool in good shape, you will not only avoid the hassle of using algaecide but also the possibility of having to completely drain the whole of your swimming pool just to get rid of algae.
