Salt pool green water

En Ok Pool Reform and within Guide to maintaining pool water We offer you an article about: Is the salt pool exempt from having green water?

What are algae?

Algae are microscopic plants in your pool

Algae are microscopic plants that can appear in the pool due to natural elements, such as rain and wind, or they can also adhere to something as common as beach toys or swimsuits.

Why does algae appear in the pool?

Know the causes of why algae appear in the pool , types of algae according to their color to be able to permanently treat them and how to prevent algae proliferation.

Then We list the main reasons why pool water turns green and then we present each product one by one..

Is the saline pool exempt from having green water?

Saltwater pools are not immune to algae

Saltwater pools are not immune to algae, as an example, the concentration of salt in seawater is ten times higher and they coexist there.

If you keep your salt chlorinator in good condition and maintain a maintenance routine you will not have problems with the development of algae.

• El Saline Chlorinator If it works well and has the necessary amount of salt, it does not cause problems since it generates enough chlorine to keep the water in proper condition.
• However, it is advisable to add each week Algae as prevention to avoid the development of algae.

To eliminate green salt pool water, the super chlorination of the electrolysis equipment is not useful

What is the super chlorination function in salt pools?

Super chlorination can be used in most saltwater chlorinators, which have the option to increase chlorine production to 100 percent for 24 hours.

Doing so increases chlorine production, immediately raising the concentration of free chlorine in your pool water.

Do not use the equipment's Super Chlorination to eliminate algae

So, as we have just argued, Super chlorination boost mode is not strong enough to address algae problems.

Super chlorination function: increases chlorine levels gradually and at a lower concentration

• So, the super chlorination function increases chlorine levels gradually and at a lower concentration, especially if your generator is already running at 50% or more of its maximum output.

Real uses of increasing chlorine production in salt electrolysis

• This mode is designed to be used whenever your pool experiences a large number of swimmers (many swimmers), rain increases the water volume, you have added more water after evaporation, or your water looks a little cloudy.

• You will also apply excess chlorine weekly, just as you would add shock to a normal chlorine pool to remove chloramines and contaminants introduced by swimmers.

Bet on shock treatment if you have green water salt pool

Superchlorination and shock treatment are very similar

Superchlorination and shock treatment are very similar because they both raise free chlorine levels, but they are not technically the same.

Green water salt pool will be much safer to carry out shock chlorine treatment

Therefore, In the case of having a green water salt pool, it will be much safer to carry out a shock chlorine treatment., by virtue of the fact that it raises chlorine levels almost instantly to the chlorination breaking point.

Consequently, a very high level is designed to eliminate chloramines and other harmful microorganisms such as algae or commonly called green pool water.

How is the treatment of a green salt pool different from that of a pool disinfected with chlorine?

Process to eliminate green salt water from the pool, the same as for a chlorinated pool.

The process to eliminate green salt water from a pool is exactly the same as for a chlorinated pool.

Option to use to combat green water with shock calcium hypochlorite

Just remember to use a calcium hypochlorite shock treatment in case you do not want to stabilize the pool, that is, apply isocyanuric acid that contains chlorine and that we avoid with the salt system.

Not stabilized (calcium hypochlorite): much more unstable, must be handled with care. It does not have a stabilizer, so it is much more sensitive to the effects of the sun.

Control of pool alkalinity levels

Firstly, As long as necessary, the alkalinity value of the pool is corrected first and then the pH of the pool water.

What is pool alkalinity

To begin, explain that the alkalinity is ability of water to neutralize acids, a measure of all alkaline substances dissolved in water (carbonates, bicarbonates and hydroxides), although borates, silicates, nitrates and phosphates may also be present.

Alkalinity acts as regulatory effect of pH changes.

In our entry we have dedicated a section to answer questions about the pool alkalinity:

• How to lower pool alkalinity
• How to increase pool alkalinity
• The Difference Between pH and Total Alkalinity

Pool water alakalinity meter

Parameters to review alkalinity of water: The ideal range is 80-120mm.

• If the alkalinity of the water is not correct, it may cause the disinfectant to not work either since: it imbalances the pH, it can form scale on the wall, among others.
• To check this parameter there are different analytical strips on the market, you can take the water for a complete analysis at a pool store...

4nd step remove remove salt pool green water

Perform shock chlorination in the pool

Shock chlorine dose depending on the amount of green algae present

Check product label

Determine the recommended dosage for your pool size and then adjust the treatment based on the type of algae in your saltwater pool:

Double shock treatment of a chlorinated pool if there is only a little algae

Apply triple shock chlorine twice that of a chlorinated pool if there is a lot of dark green algaei

How to perform shock treatment

1. Apply shock chemical: shock chlorine (minimum 70% chlorine).
2. Most common chemical product for shock treatment: Liquid or tablet shock chlorine, Active oxygen, Liquid oxygen.
3. Carry out shock chlorination to the pool: adding 20 g or 30 g per m³ of water depending on whether there is a small amount of green algae or a lot and according to the specific shock chlorine product (which you can find in different formats: granulated, pills, liquid...).
4. We fill a bucket with water according to the product instructions and m3 pool water.
5. Stir the water in the bucket so that the product is dissolved.
6. Pour the contents of the bucket near a pool return nozzle, little by little, so that it mixes.
7. . Filter for 12-24 hours.
8. Once the time has passed, we will check the pH again since we will probably have to adjust it (ideal pH value: 7,2-7,6).

How to perform shock chlorination of liner pool

• In the case of wanting to do shock chlorination for a liner pool: above all, it will be very important to dissolve the appropriate dose. in a container before spreading it in order to avoid damaging the liner.

5nd step remove remove salt pool green water

Filter for 12-24 hours

Continuous filtration after shock treatment

• The high dose of chlorine and dead algae spores suspended in the water will make it look really cloudy right after the method.
• Therefore, After chlorination, keep the filtration running for 12-24 hours straight.
• In short, the goal is to operate your filtration system until we see that the water is clear.
• So, we monitor the results as the hours pass and if after 8 hours the water still looks quite hazy, we will add a clarifier and let the filter run for at least 6 more hours.

6nd step remove remove salt pool green water

Filter cleaning

How to clean the filter

Cleaning the filter is done in two parts, washing and rinsing. And with these actions we clean the filter from the inside, throwing all the dirt that is trapped in the filter medium into the drain.

Your filter has been working overtime to get rid of algae spores, so we'll need to make sure it doesn't allow old algae to come back through the return lines.

Cleaning the filter using the pool selector valve operation

• Pool purifier selector valve = Control of all the functions of the pool purifier thanks to its control method.
• In this way, the fPool purifier valve key functions: filtration, washing, recirculation, closed, rinse and empty position.
• If you use a diatomaceous earth or sand filter, you will need to backwash it to remove it and then determine if it is time to replace the filter media.

7nd step remove remove salt pool green water

We take the water chemistry values ​​again

Check if the values ​​need to be adjusted again and repeat the treatment.

• There are many times that you will have to adjust the values ​​again and repeat the entire treatment again., although it also depends on the life of the pool water and how saturated it is, out of adjustment... that you may have to change the water partially or completely.

8nd step remove remove salt pool green water

Consider whether it is necessary to renew part of the pool water

Renew a part of the volume of water

If the previous steps have not borne fruit, the essential objective of renew a part of the volume of water (about 1/3 of water) which essentially includes this surface and bottom cleaning operation.

After treatment, how long does it take for the green water in the salt pool to disappear?

The total disappearance of the algae can last several days

The total disappearance of the algae can last several days depending on the state of the pool water. Therefore, this process must be repeated several times until the water reaches the correct values ​​of Alkalinity, Chlorine and pH and its appearance is adequate.

How long on average does it take to lighten a green pool?

The quickest way to clean a green pool is by using pool chemicals and your pool filter. This process usually takes 4-5 days, but you will start to notice significant improvement after 24 hours.

Prevent algae in our saltwater pool

Prevent green pool water by knowing how your salt chlorinator works

What is salt chlorination

Salt chlorination or salt electrolysis is an advanced sterilization and disinfection system to treat swimming pool water with saline disinfectants (through the use of chlorine or chlorinated compounds). 

La saltwater pool the water is actually chlorinateda

In reality, the Saltwater pool water is actually chlorinated, in fact it has (ideally) the same amount of free chlorine as any normal pool.

Therefore, find more information in the entry dedicated to: What is salt chlorinator (salt water pool)

Ideal chemical values ​​to maintain in the saltwater pool

Maintain ideal water chemical levels to avoid salt pools with green water

Operation Salt water chlorination

How the saltwater pool works

• the water is actually chlorinated. In fact, it has (ideally) the same amount of free chlorine as any normal pool.
• The difference lies in how the disinfectant is administered to your pool water.
• With a saltwater system, you put salt into your pool instead of chlorine.
• Your salt chlorine generator then removes (super technical term) the saline solution (salt water), converting the salt into hypochlorous acid (HClO) and sodium hypochlorite (NaClO), the compound commonly known as chlorine.
• Because the electrolysis (zapping) process occurs when salt water passes through the chlorinator, chlorine is added slowly and steadily throughout the day. Your chlorinator will never deliver a massive dose of pure chlorine to your pool at once, making the water softer and gentler on swimmers' skin, hair, and eyes.
• Then, we also suggest that you review the entry of the Saline chlorinator maintenance: learn everything about how a salt chlorinator works, maintenance to be performed, start-up...

What is better salt water or chlorine pool to disinfect pools?

Indeed, it is better Disinfecting swimming pools with a salt chlorinator without the use of chlorine is a decisive advantage for the health of the skin and respiratory system that increases the beneficial sense of swimming in pools free of sodium hypochlorite and chlorine.

Advantages of salt pools

Next, we will tell you The advantages of saline electrolysis equipment, that is, an electrical water disinfection system that dissolves the salt in the water to be treated.

Main advantages of salt chlorinator

• The use of a salt chlorinator to purify a pool with salt water will help you enjoy a clean pool, without bacteria, fungi, or any type of health risk due to the presence of pathogenic or toxic agents. It is a reality.
• Thus, salt chlorinator is not irritating to the skin.
• In addition, it is a natural treatment that does not represent any danger, since it purifies pool water without the use of abrasive chemicals.
• Likewise, salt has no odor and is effective as a guaranteed product to achieve water quality naturally and without chemical problems.
• It is a natural product that is very easy to use, it works like an electrolyzer to treat water in an automated way.
• Users of salt chlorinator gain benefits because it does not contain irritants for people's skin and mucosa.

Video with benefits of salt chlorination

Disadvantage of salt water pool

In salt electrolysis, if the chemistry is not maintained, algae proliferation is easier.

• Because the electrolysis (zapping) process occurs when salt water passes through the chlorinator, chlorine is added slowly and steadily throughout the day. Yes
• So, a chlorinator will never provide a massive dose of pure chlorine to your pool at once, making the water softer and gentler on swimmers' skin, hair, and eyes.
• The downside is that it can also facilitate algae growth if you let your pool chemistry decrease even a little.
