How to Get Rid of Pool Algae in 13 Simple Ways

Gradually, a large pool has become a common thing in suburban areas. Open variants of swimming facilities are very popular. Taking care of a pool can be challenging. For example, if not to clean it regularly and properly it can bloom. No one wants to swim in muddy green water that is full of threads.

Weeding can be a common problem for pool owners. That’s you need to consider not only filters, nets, and skimmers but also various reagents for pool treatment. Maintenance, as well as the control of sanitation indicators, can help you avoid unpleasant consequences. Any pond blooms, when it is located outside. In most cases, the process of weeding is caused by natural debris.

To avoid it, you need to get rid of simple microorganisms that make the pond unsuitable for bathing, being dangerous to human health but also damage the condition of filters. Small kids, having a lot of energy, actively swim, dive, and may swallow water.

If there are algae, closing for disinfection treatment is a must. It should be done to avoid health problems such as the digestive disorders, poisoning or symptoms of an allergic reaction. Moreover, the skin surface may suffer as well. It is possible to experience such unwanted skin conditions as rashes and itching.

Sure, algae, if they are not removed on time, cover automatic filtering equipment easily. This problem involves a need to change the filler of a filter and include back washing. In addition, algae can contribute to equipment wear. However, there is nothing impossible when you know how to make your pool look good using a right pond cleaner and a skimmer.

No need to fall into panic. Just follow these step-by-step instructions. You’ll be able to cover preventing automatic algae appearance and get rid of existing weeding effectively if you rely on these tips and implement them.

To get rid of millions of algae, you should have a clear picture of what algae are, why they appear and what are the possible reasons for their appearance. These are spores of unicellular and multi cellular microorganisms, which cover huge distances with an amazing speed spreading unlimited. Their best ability to survive has been developing during millions of years. Keep in mind that the warm temperature in your outdoor pool is an ideal environment for them.

Step 2: Differentiating Types of Pool Algae

Green algae: a large group of green algae appears if there are such factors as a lack of chemical reagents in the water, there is a little movement of water, it is poorly filtered and not often renovated. Green algae settle at the bottom of your pool in a form of the soft mucus.

Yellow mustard algae: yellow mustard alga is difficult to remove with a vacuum. To eliminate it, you'll need a shocking volume of chlorine. Perhaps, this is due to the fact that they are stable to a normal value of chlorine. Yellow algae actively spread in those places where there is little sun, which is why it is possible to look for them in a shaded part of your pool.

Black algae: black alga is the most persistent and stubborn. It settles in welded seams of the membrane, when there are holes around. Nevertheless, the existence of a black type signals that there is almost no chlorine in your basin.

Step 3: Have Regular Tests of the Pool Level

It happens that the owners lack energy, time or desire keep an eye on the pool and protect it from bacteria, fungi, and algae daily. As a result, they begin to spread actively producing carbon if sanitizes aren’t applied.

These harmful organisms fill an entire pool area and cover all free parts of a surface. No filter unit with a swamp can cope with them. You’ll have to drain, process your tank mechanically, change filters, add substances that stop the growth of algae and fill your pool with water again. If the spread of black algae is moderate, then you’re to follow recommendations below to kill them and refresh water. To do this, you should test your water.

Before you’ve started cleaning your pool from sand or alga you need to evaluate your current water parameters. First make the main measurements of PH level, chlorine, salts. For testing alkalinity balance conditions, find the suitable pool testers. For eliminating of algae parts or better their 100% killing, it is necessary to maintain the level of reagents, in particular, chlorine, at a stable level, which can kill even black algae parts.

Step 4: Clean Walls and Tiles Mechanically

Are you depressed and think about the pond closing? Use your pool vacuum to clean the surface from black algae. Rinse filters, backwash, then turn it on and let water run until the entire pond is completely purified. A regular process may take 12-15 hours. If necessary, replace your cartridge and check out the PH level.

Step 5: Apply a shock cleaning every month

Turning to balanced shocking purification implies an introduction of a shock dose of disinfectant based on chlorine, for example, calcium hypo-chloride. If it exceeds a usual dose for your pool four-seven times, get a calcium hypo-chloride solution and leave it to work overnight.

If there is a severe contamination, you may need to clean it again. Then you need to carefully brush your bowl and a bottom of your pool eliminating dead algae because they will sink into the bottom or swim on the whole surface above. Apply shock purification as often as possible. It is not as difficult as it may seem: just brush your filters to free the pond from alga. Finally, prevent the algae growth by adding an anticoagulant.

Step 6: Replace Old Water

The most effective way to quickly and efficiently clean the dirty pool is to replace old water completely. To do it in a proper way, get a small electric pump or another suitable pump. It is possible to use even a simple bucket.

Important! What to do to avoid the constant water change? It is necessary to avoid using the tap water, in which there are spores. In the well or a tap, there is a circulation of algae spores.

Step 7: Determine the Lack of Certain Chemicals

Adjust the value of indicators by adding an accurate a dose of an acid or an algaecide.

PH <7 - Acid environment - Dangerous for machinery and equipment

PH = 7 - Neutral

PH > 7 - Alkaline - Causes loss of salts, is the reason for an unpleasant smell of water, may cause an eye irritation.

Pay attention to a piece of advice from the specialists who do cleaning of pools: for each disinfectant, it is required to test its pH level to meet the conditions of its greatest effectiveness.

Step 8: Use Copper Sulfate

Consider several functions of this chemical element:

  • check
    Works magic by killing all the algae
  • check
    Kills fungus together with its spores
  • check
    Promotes removal of small algae from a pool

Copper sulfate refers to dangerous products that should be used carefully. If it is incorrectly dosed, you may risk getting severe burns on a skin. That's why you should consider dosage and safety instructions when opening a package.

For the elimination of the black algae, copper sulfate must be diluted on a basis of a small amount of cloudy liquid in a container. The solution of phosphates should be poured into the running pool. The safety concentration of your copper powder should not exceed 0,9 gr. per 1000 liters. You can try to improve an effect if you mix salt and copper sulfate sticking to the ratio of 3:1. To act as a weeding reducer, copper sulfate is mixed with peat and covered in cloth bags, after it is immersed in a pond.

Remember that copper sulfate cannot destroy a layer of natural pathogenic environment and microorganisms. For these purposes, it is better to have a chlorine dioxide or bromine. A solution of copper and common salt is effective as it greatly reduces the turbidity and helps to remove algae properly.

This liquid can help remove alga from walls of a pool. One more good idea to try fighting against dangerous microbes is to use special chlorine tablets for ponds that can be bought online or in the specialized stores.

Step 9: Darken an Open Pool

There's a direct relationship between an organism of algae and an intensity of light. The more hours the pool is heated by the sun rays, the more often a pond will bloom, and algae layer will spread more intensively.

Therefore, it is recommended to make an open pool dark weekly. To do so, trees are planted on one side. It is possible to build a water structure taking into account the blackout. Reduce an effect of direct light to 3-4 hours a day. If you keep your pool completely dark, then your dark pool will not have time to warm up.

Step 10: Add a Substance Preventing Algae Growth

Use algaecide aimed to prevent the development of algae in winter and spring. At the same time, add algaecide that does not change the PH value but brightens the pool water and destroys the bacteria, since a variety with a bactericidal effect is also available. It is desirable to have all algaecides, phosfree, and flocculants in the pool water weekly because it is possible to prevent an emergence of particularly resistant dry roots of black algae, especially during winter/spring.

Step 11: Use Ultraviolet and Ionization of Water

  • check
    Ultraviolet will help you forget about pollution. But if the water has already bloomed, ultraviolet rays cannot penetrate the green suspension at vinyl siding.
  • check
    Ionization is a low-voltage current that passes through the liquid. It releases copper ions, which “brushes” negatively affecting the development of floating pool algae.

Step 12: Install the Filter

Prevention is always less effort-consuming than treatment. Some people think that it is enough to use a filter. However, it is recommended to use it as one of the methods. Otherwise, it will be low-effective. Not all filters can catch spores of the black seaweed organism.

Those that can do this are expensive and require constant cleaning. In outdoor pools, even the most expensive filter will not give one excellent results since spores of algae come from the outside. However, if you can use a filter as an additional filtration method, then it will definitely be a benefit during winter.

Step 13: Keep the Water Condition and Brush the Pool

Be sure not to forget to weekly test your pool system condition. Treat a pool system twice a month both mechanically and chemically brushing with an appropriate sanitizing product. Cover all methods to eliminate unwanted effect or at least a combination of a couple or any three most suitable ways. Keep in mind how to carefully remove pool dirt with the right chemicals. You'll need to process the pool properly.
