Will My Swimming Pool Turn Green If I Dont Add Chlorine

How To Clear Up Green Swimming Pool Water Pt. 1

Simply put, Yes!

Swimming pool water must have a sanitizer that will kill bacteria and algae. Algaecide alone without chlorine will not prevent the pool from turning green.

In order to stay on top of maintaining your pool and ensuring that it remains as blue as possible, you need to be shocking your pool water with chlorine every week or so.

Which Method Is Best

We would choose Method #1: Getting Rid Of Pool Algae By Shocking every day of the week. By using this method, you’re keeping it simple by focusing on chlorine and acid, while using your filtration system to bring it back to life. It tends to be a bit of a work-in-progress and can take 1, 2 or even 3 weeks, depending on the state of your pool, but it’s definitely the easiest.

We also personally like to recommend keeping an algaecide on-hand year round for monthly dosage. If your pool is clear and balanced, an algaecide will do its part in keeping any green, black or mustard algae bay during a chlorine or pH fluctuation.

Run The Pump & Adjust Calcium Level

Turn on the pump and let it run for at least 8 hours. Calcium is your friend in the fight against copper, so use calcium chloride to raise the level to 350 ppm if its low.

With calcium chloride, 2 ounces per 1,000 gallons will raise the ppm by 10. So if you want to raise it 50 ppm, use 10 ounces per 1,000 gallons.

Run The Pump And Filter The Water

Verify that the water is able to properly complete its journey through all the circulatory equipment, and the filter pressure is at normal levels. Once youve achieved good circulation and filtration, let the system run before you give the pool a test swim. The amount of time the equipment will take to totally clear the water will vary depending on what type of filter you use anywhere from a few hours if the filter uses diatomaceous earth, to several days for a sand filter. As a general principle, change out paper cartridge pump filters regularly. You can make these filters last longer by washing them out with a hose and soaking them overnight in a bucket of white vinegar or bleach. If you use a sand filter system, be sure to perform a back flush according to the manufacturers recommendations.

Test Copper Ph And Calcium Levels

Using a test strip thats specific to copper, dip it into the pool to find out the amount of copper in it. Ideally, you want it to be at zero. Next, test the pools pH level with a regular test strip or liquid test kit.

A pools balanced pH should be between 7.2 and 7.6. Finally, use a calcium test strip to find out the level of calcium hardness in the water. In general, youll want this level to be 250 ppm.

First Balance The Chemicals

Before adding chemicals to kill algae or other harmful pathogens, its vital to check the pH and alkalinity levels, which should be between 7.2 7.8 and 80-120 ppm. Any pH level higher then 7.8, depletes its effectiveness. You can try a pool test kit to know these levels. If its below the recommended level of a minimum of 7.2, then add sodium bicarbonate. However, if the pH is above 7.8, then use dry acid or muriatic acid to get it down. To know the exact amount of these chemicals, check out this handy tool thatll do the job for you.

Why Is My Pool Green

First, you should know the only thing that can turn pool water green is Algae. Algae can grow for a handful of reasons: when the pool is lacking in circulation, the water is warmer than normal, or if the chemicals are out of balance. Sometimes, algae can grow during the winter and is often found when you go to open up for the summer. When you find it? You may be asking yourself if it is even safe?

Two: Test And Adjust Ph Levels

How To: Clean A Green Pool

Before adding any chemicals to kill the algae, its crucial that you check the pH levels and adjust accordingly. Using a pool test kit or pH strips, determine the current pH of your pool. It should be between 7.2 and 7.8.

If the pH of your pool is above 7.8, the chlorine in the bleach will not be effective at killing the algae. To clean your pool effectively, the pH level must be between 7.2 and 7.8. If its below 7.2, youll need to add in sodium bicarbonate. Whereas, if its above 7.8, use muriatic acid or dry acid to lower it.

Cause #: Environmental Effects

If your cloudy water has nothing to do with the chemicals or the filter system, then the only reasonable explanation left is that its being caused by the surrounding environment.

Yep, Mother Nature can be a real b*tch sometimes. Here are some of the likely environmental causes:

Leaves & Small Debris

While leaves will be easy enough to remove before they dirty up your water, its really the build up of smaller dust and particles that can get you into trouble.

Small Animals & Insects

Insects and small animals will always find their way into your pool eventually, but the biggest things to keep an eye out for is droppings, particularly bird poop.

The Dreaded Algae

Insects and small animals will always find their way into your pool eventually, but the biggest things to keep an eye out for is droppings, particularly bird poop.

Surface Runoff

Heavy rain can cause water to accumulate on the ground, in some cases making its way to your pool bringing plenty of other nasties with it .

Dont forget On top of all this, you also have to account for the countless things that we humans take into the pool every time we decide to go for a little swim. Thats right, youre not as clean as you like to think.

Why Use Bleach To Clean A Green Pool

Instead of purchasing expensive pool cleaning products, bleach can be used as an effective and convenient alternative for cleaning a green pool. Some of the benefits to using bleach for pool maintenance include:

  • Bleach is less expensive than liquid chlorine.
  • Bleach disinfects and sanitizes your pool.
  • Bleach is safer to use than chlorine tabs.
  • Bleach oxidizes ammonia and other wastes excreted by swimmers.

There are a number of different types of algae. The class that turns your pool green is known as Chlorophyceae, or Green algae. Therefore, bleach is the ideal product for cleaning a green pool since, unlike other algae types, Green algae are not resistant to the chlorine found in bleach.

If you have green pool water after shocking your pool, then you may have too much copper in your water. You may have copper naturally present in your water source or it could be coming from the plumbing. You will need a chelating agent to clear up your water. Once you have treated your water with this, test your other chemicals again to make sure none of them were thrown out of balance.

Generally speaking, it is best to use one or two pounds of shock for every 10,000 gallons of water.

Green pool water is often caused by the presence of algae in your pool. Learn how to treat algae and get rid of green pool water.

Green pool water is often caused by the presence of algae in your pool. Algae blooms can appear when your pool has a low Free Chlorine. Exposure to high heat, heavy rain or poor circulation, without the use of a preventative algaecide, also increase your risk of developing pool algae. Stubborn pool algae can be hard to control if the appropriate steps arent taken to properly treat and prevent the problem. Follow these steps to treat and prevent green pool water.

Test and Balance Water

Always begin by testing your pool water. Your test results will tell you if your water parameters are unbalanced. Pay special attention to your Free Chlorine level. Low Free Chlorine can cause your pool water to turn green. Always maintain Free Chlorine between 1 -4 ppm. If needed, apply the appropriate chlorine and sanitizers to restore adequate sanitizer levels.

Clean Pool Water and Surfaces

Skim water surface to remove visible debris, brush walls, vacuum and empty skimmer baskets. Concentrate on areas with visible dirt and little or no circulation. Cleaning your pool regularly is an effective step to prevent algae growth.

Apply a Shock Treatment

Crystal clear water starts by applying pool shock. Shocking your pool water helps to remove contaminants that may cause algae to grow and helps to improve water filtration.

Apply an Algaecide

How Do You Clear A Green Swimming Pool

As your pool is most likely green due to a lack of chlorine, you should first try to boost the chlorine levels in your pool as soon as you have a chance.

The longer you leave it, the more likely that youll need professional help to clear your green pool.

In addition, you should think about adding an algaecide supplement to this chlorine shock if the algae growth is severe.

You can tell the severity of the problem by simply observing how dark the water has become. One pool shock treatment should be sufficient to clear it if your pool is only a light green.

However, its worth noting that a shock treatment may not always be enough to restore your green pool back to blue if its become a darker color. This might be the case if the water is a dark, black-looking shade of green.

In this circumstance, the pool has been left untreated for too long and will therefore require professional pool treatment. At this point, you will need to get professional help to tackle the issue.

In severe cases, the pool will need to be drained and thoroughly cleaned by a qualified pool service engineer to get rid of the problem.

Once the algae have been dispersed, you might notice that your pool water still looks cloudy. However, this shouldnt alarm you.

Once youve run the pump and filter for a full 24 hours, you should notice the water slowly returning to normal.

Your above-ground pool is green. You probably are getting ready to start enjoying it again after a break or just fell behind in caring for it. How do you get it back to the natural blue color that you are used to swimming in?

Lets examine it step by step and discuss how you can keep it from getting that way again. When all is considered, maintenance over the long term is the best way to prevent algae so we will help you discover whether you can do this on your own or if you need help from someone to care for your pool.

Cause #: Circulation & Filtration Issues

My Swimming Pool is Green How can I Fix it?

Pool water that isnt being properly circulated is always at risk of becoming cloudy water.

Thats because circulation pushes your pool water through your filter system, so without it, the filter cant work its magic and keep your water squeaky clean.

There are a few moving parts to this, so lets go through them.

Is Your Pump Powerful Enough?

A pool pump is a core part of your filtration system as it cycles your water through the filter in order to remove debris and maintain circulation, this prevents the water from stagnating which eventually breeds other problems.

With that in mind, you need to make sure your pump has the ability to cycle the entire contents of your pool at least once per day. Whats more, youll need a pump that can complete a turnover in an 8 hour period.

The speed at which a pump completes a turnover is based on two factors:

  • The volume of water in your pool
  • The flow-rate of the pump itself
  • Note: Flow-rate tells you how many gallons of water pass through the pump each minute, and its appropriately measured in gallons per minute .

    To properly size your pump, divide your water volume by 8, then divide again by 60. What youre left with is your pools required turnover rate in GPM. The flow-rate of your pool pump should be at least the same.

    Is Your Pump Suited To Your Filter?

    You wouldnt put all that effort into correctly sizing your pool pump only to neglect your pool filter, would you?
