How to Treat Green Water Swimming Pool

May 08,  · If the pool has been shocked and is no longer green, but turns green again after a day or two, check the water chemistry and pay particular attention to phosphates in the water. Clean the filter often during this process. After shocking the pool, filtration becomes a key factor in clearing up a pool. To eradicate Green Water Swimming Pool issue by using chlorine shock method, first we need to drain the swimming pool. After it is drained, we can see some areas on the pool tiles that have overgrown algae. The indication is pool tiles turns green like there is moss on it. To get rid out of this, we can spread or pour chlorine on these areas only.

Treating a pool that has turned green? This article will take you step-by-step through how to get that nasty pool in shape. I will also cover some basic chemistry and filtering tips to prevent this from happening again.

All information is based on an in-ground home pool of average size, from 12 to 15 thousand gallons. Algae make it green, and a chemical imbalance lets the algae grow. If there is enough free chlorine in the pool, algae will have a hard time forming. That's why you shock your pool with chlorine as part of the six-step process below.

If the green comes back, you can adjust the levels how to treat a green swimming pool other chemicals besides chlorineas there is more to pool how to hack trend micro internet security chemistry than chlorine alone. Each of these steps is described in detail below. I have seen many pools that were not just green, but black. In severe cases like this, it is more cost-effective and less time-consuming to simply drain the pool and have it acid-washed, even though it costs money to refill the pool.

This is my general rule for determining whether the pool can how to download songs from dhingana treated chemically or needs to be drained: if you can see at least six to eight inches below the surface of the water, most likely the pool can be treated chemically.

An example is in the photo below; you can see the top of the first stair down into the pool. Once we establish that the pool doesn't need to be drained and can be treated chemically, we can go from there.

An example of green pool water that can be treated chemically. But you should test for pH, because if the pH is very high, the shock will turn the pool cloudy. A shocked pool will be cloudy anyway until all the dead algae and other solids are filtered out, but high pH will cause a VERY cloudy pool.

To find out the pH, I prefer to use a high-end test kit, but the cheap test strips will at least give you an idea if your pH is high or low. You want it to be low: 7. If the pH is high, add one gallon of muriatic acid, which should be enough. Don't worry that you may have added a little too much, because the pool can be a little acid low pH for swimming purposes but still at a good pH for shocking. Test the pH again after shocking and four hours of circulation. Once your pH is 7. I suggest purchasing a pound container of granular chlorine, rather than the individual one-pound bags they sell at pool stores or large chain stores.

You'll save a great deal of money, and you will need chlorine in the future for small doses from time to time. Use five pounds of granular shock, or 10 gallons four 2. With the filter pump on, broadcast the chlorine evenly over the water, covering the entire pool surface, until all five pounds of shock, or all ten gallons of liquid chlorine, have been used. Be sure to use a good algaecide as well, which you can add after a few hours of circulation.

You can also add a floccing agent at this point to cause the dead algae particles to clump together. I wrote a follow-up article about shocking the pool that answers some of these questions in more detail:. After 24 hours of chemicals and circulation, you will see an amazing transformation. Your pool should not be green anymore.

But it will still be cloudy, and it will need a lot of brushing and filtration for the next few days. There will probably still be a few stubborn isolated green areas that need some brushing.

Question: I shocked the pool, and then waited over 12 hours to go in and how to view private photos on myspace 2013. At this point, the water was a blue cloudy.

Towards the end of vacuuming, the pool is now green. I backwashed the filter, and let the pump run for over 12 hours. This morning I went out, it's still green, but clear enough to see to the bottom of the pool. I can see what I believe is algae on the pool floor. But I know if I go in to vacuum, it will be green again. What do I use, what do I do for this? Answer: So what is happening is that when you vacuum, much of the "green" is shooting back into the pool. You mentioned backwashing, so you either have a sand filter or a de filter.

If a sand filter, this makes sense. Some systems just have a valve to open to drain the pool, but depending on the plumbing, sometimes when this is open, some flow can continue through the filter and out the pool returns even though some of it is going to waste.

If you can't vacuum all to waste, keep the filter clean daily and the pump running for as long as it takes to filter out. But it sounds like you need a floccing agent and a way to be able to vacuum to waste.

Check this article on using a flocculant:. Question: My pool was so clean all the time, but I changed to another company, and my pool is too green. The company says that somebody used sun creams inside the pool, but they haven't fixed the problem yet. What can I do?

Answer: Suntan oil, lotion, sunscreen, etc. Cartridge filters absorb this the most. Sand filters are not highly affected by this. DE filters will absorb all of the oils, but will just need to be backwashed more frequently. What can you do? Keep the filter clean. Make sure there is plenty of flow. As long as the chemicals are balanced, how to install california closets make sure the pump and filter are flowing at full capacity.

Sunscreen type of products will cause build-up on the filter reducing the flow. Clean or backwash your filter. If it's a cartridge filter, the cartridge may need to be replaced. Answer: Try checking these things: The filter. Make sure it's clean, and there is plenty of flow. Chemistry: Have the water tested for phosphates and treat as needed. Check the stabilizer and make sure it's under If the chemistry is balanced, I suspect a bad filter and lack of flow.

Question: The pool store measured my copper level at. My pH was high, and the chlorine was low. I poured a bottle of Metalfree in but after 24 hours, there was still no change.

Do you have any suggestions? Answer: I would question the integrity of the pool store you visited since copper will not turn a pool green. It sounds as though you were the victim of an "upsell". Although it is good to keep your pool free from metals, this is not why the pool is green. Low chlorine and high pH makes more sense.

To balance the chemistry pH, chlorine, and alkalinityI recommend the pool also be tested for phosphates. Make sure the pool filter is clean and working properly with good flow. Does the cartridge filter element need replacing? Is the sand filter working properly? Is the DE filter holding the DE powder? If you have an in-ground pool with a concrete type surface with a serious copper problem, then blue or teal color stains will be visible.

A vinyl liner will make it difficult to detect any "metal" type effects. Answer: This is a chemistry issue. If the pool turned green immediately after how to treat a green swimming pool the pool, then there what age to cut puppy nails an imbalance with other chemicals or something else has been added how to get rid of a chalazion overnight the water that should not have.

If the pool has been brushed and shocked, it will take a few days to filter out the "green" and for water clarity to improve. If the pool has been shocked and is no longer green, but turns green again after a day or two, check the water chemistry how to make dreads grow pay particular attention to phosphates in the water.

Clean the filter often during this process. After shocking the pool, filtration becomes a key factor in clearing up a what meat for beef kabobs. Question: Can water temperature be too high to get accurate chemical readings from a pool?

Answer: No. Even in a spa that usually runs degrees Fahrenheit, an accurate chemical reading will be available. Warm water will not create any false readings regarding what is overcrowding in schools provided the test kit being used is not out of date.

DPD test kits kits that use liquid "drops" rather than dry test strips have a shelf life. Question: I have an above ground Hayward sand filter. Does it have a vacuum to waste system? Answer: If it has a multi-port valve that has a "waste" position, then yes. If it is a plunger type backwash valve, then no.

Why Do I Have Green Pool Water?

Decrease your pH level. To fix a green pool, you’ll need to start by decreasing the water’s pH level. This can be easily done with a pH decreaser. Follow the instructions on the pack to get the right pH level you need for a healthy pool. Previous Step Next Step. Mar 03,  · If your pool is very dirty, it may need MANY gallons of liquid chlorine (shock) over a period of days before the water clears.

However, we can not just add the chemicals into our pool water without any consideration. There is specific dose and requirements that needs to be considered in order to make the chemicals works effectively and safe for those who swim in it. Chlorine is not a strange substance in in swimming pool maintenance. This is generally used in the regular pool maintenance.

But, we need special treatment called chlorine shock. To eradicate Green Water Swimming Pool issue by using chlorine shock method, first we need to drain the swimming pool. After it is drained, we can see some areas on the pool tiles that have overgrown algae.

The indication is pool tiles turns green like there is moss on it. To get rid out of this, we can spread or pour chlorine on these areas only. Focus on the gap between tiles or mosaic, because this is the place where algae usually start to grow. After this step is done, you can fill the pool water again. Then, the next step is re-organizing the chemical composition in the swimming pool. Again, before doing it you need to consider the safety aspect.

To reorganize the chemical composition, firstly we need to adjust the PH into standard level. If the pH level is above 7. After PH is in standard level, pour chlorine again for shock treatment.

For your information, there are many forms of chlorine. You can find it in form of tablet, granular, or liquid. However, Liquid Chlorine is more appropriate for this shock treatment. About the dose, again, you need to consult with experts. Usually, dose will be adjusted to pool size and water volume. If it is still so difficult to remove algae using chlorine shock treatment, then algaecide can be a good option to consider.

Yes, Algaecide is made for this purpose, so people prefer to use algaecide than doing chlorine shock due to the effectivity.

However, the use of algaecide to remove algae in swimming pool is relatively pricey. This substance is usually offered in expensive price compared to the regular chemicals. And one thing to consider is that usually, algaecide is made for specific type of algae.

So, you need to pay more attention on what type of algae that causes you Green Water Swimming Pool issue, in order to get the best fit of algaecide. Just like when we do chlorine shock, in applying algaecide we need to drain the pool water first. After the pool is drained, then we need to brush the pool floor and wall using iron or nylon brush.

After brushing process is finished, we can fill the pool water again, then adjust the PH into standard level 7. Add chlorine in larger dose as in the shocking treatment. In the meantime, make sure the filter system continues to run for 24 hours straight.

Wait for 12 to 24 hours, and see if the algae that sticks on the surface or bottom of the pool are lifted. After the algae dies and lifted, the color will turn white or grayish. Use a vacuum cleaner to remove the debris and remnants so that they do not flow to the filter. After this process is done, we need to test the chemical composition on the water. It should be; chlorine is within ppm, Ph level is within 7. After this composition is achieved, you can add algaecide chemicals every week to prevent the return of algae growth.

Avoid using the pool until the algae is completely dead and the chlorine level has been at a safe level 3 ppm or less. Those are the steps that can be done to solve and prevent Green Water Swimming Pool. However, as mentioned before, those steps are not simple and require guidance at first.
