How To Test For Phosphates In A Pool

How To Test For Phosphates In A Pool

As a pool or hot tub owner, you would need a phosphate test tube at some point in time.

When you get a phosphate test tube, what you see inside a pack is a test tube, a test strip, and a chart. What you do is fill the test tube with the watermark on it, fold the test strip into two and put it into the cover of the tube, then cover the tube.

Turn the tube upside down and then back up about five times. After that, keep the tube on the white parts of the chart to know the phosphate level. Keep comparing the water color to each white color on the chart.

Phosphate should be tested during the heat of summer, in springtime when you open your pool and also before you close the pool to be sure that the water remains clean and crystal clear. Your phosphate level should not be more than 200 ppm. If so, then you should definitely use a phosphate remover to maintain clear water.

How do you test for phosphate in a pool?

But since your phosphate level is higher than 200 parts per million, it detects that the water is not clear enough. But since we do not want to jump to conclusions quickly, we would have to test the pool using a phosphate test kit. It comes with a test tube, strip, and color chart.

All you have to do is fold the test strip into two, put it into the test tube cover, and cover the tube. Turn or invert the tube slowly five times, then open and keep it on the white side of the color chart. Compare all the white colors with the water in the tube.

Once you get the perfect comparison, then you check the quantity of phosphate and use a phosphate remover to reduce the phosphate level.

What adds phosphates to pool water?

Phosphates enter the pool in a variety of ways, and most of the time you are unaware that you are indirectly adding phosphates to the water.

Phosphates could get into your pool through chemicals. There are so many chemicals we apply to our pools that have phosphoric acid. When you apply these chemicals to the pool, they solve the problems you are trying to solve and indirectly add phosphates to it.

It could also get into your pool through the tap water you used to get your pool filled. Many plumbers or tap owners use phosphoric acid to maintain their pools. Phosphate gets into the pool through organics.

Let us assume you have grass around the pool area, and you have used fertilizers that have little phosphates on the grass. You didn’t put the fertilizer in the pool directly, but things like rain can cause these chemicals to get into the pool and make the phosphate level go up.

What does adding phosphates to a pool do?

Since phosphates are found in almost everything, like rain, well and tap water, debris, and dried leaves, which are likely prone to getting into the pool, it is almost impossible to avoid its addition to the pool.

Adding phosphates to a pool increases the algae growth and makes the water green. This is because they are very helpful in the growth of these algae. So, the lower the phosphate levels, the less algae in the pool.

What causes high phosphates in a pool?

Algae feed on phosphate mainly to grow. When phosphate is found in your pool in a very high amount, more than 200 parts per million, your water becomes very unhealthy and changes to a green color.

Phosphates are found in almost everything, like rain, well and tap water, debris, and dried leaves, which are likely prone to getting into the pool. It is almost impossible to avoid its addition to the pool.

They could also be added through chemicals applied to the pool that have a phosphoric acid base. It also gets high in a pool that has not been shocked or sanitized.

Do I need to worry about phosphates in my pool?

The presence of algae in your pool should give you nightmares and make you very uncomfortable. Now to reduce this algae, then look forward to maintaining a low phosphate level.

The phosphate level should not be higher than 200 ppm. If it becomes very high, you should start getting worried and making plans to use a phosphate remover because you will not like the presence of algae over time.

What happens if you put too much phosphate remover in your pool?

You should avoid making mistakes in the process of putting chemicals in your pool because it affects other important factors needed in the pool.

When you apply too much phosphate remover to your pool, it makes the water very concentrated and makes the slit or sediments go down into the pool, making it cloudy and affecting the alkalinity.

What removes phosphates from pool water?

When you start seeing algae growing in the pool, then the presence of phosphate is confirmed.

The best thing to do to remove phosphate is to shock the pool. To prevent the shock from sitting on the pool liner, brush the pool wall first, then add the shock and brush the pool again.

After shocking, test the pool for phosphate. If it still indicates the presence of high phosphoric acid, you can go ahead and add the phosphate remover to the skimmer.

How do you fix the phosphate level in a pool?

Before you think of fixing the phosphate level in a pool, you should have tested it first with the test kit. If it is higher than 200 parts per million, then you have to work towards bringing it down.

To reduce the phosphate level of the pool, the pool should be brushed, shocked, and phosphate remover should be added. You can also choose to sanitize the pool by checking the chlorine level. Another important thing is to get rid of leaves and other trash. Also, try to close the pool when it starts to rain.

How long does it take for the phosphate remover to work?

For a phosphate remover to work rapidly, it depends on the size of your pool, the number of gallons of water, and the quantity of phosphate remover you added.

However, the phosphate remover should have been able to remove 90 percent of the phosphates in the water within 24 to 48 hours.

Is algaecide the same thing as phosphate remover?

Using phosphate remover with the aim of doing the work an algaecide should do is totally wrong and would be inefficient.

Algaecides kill algae and keep them from growing in the water, and phosphate removers help lower the amount of phosphate in the water. You are probably thinking that since the algae feeds on the phosphate, the phosphate remover will help to eliminate them.

Well, no! The two chemicals have their different functions and they work in different ways. However, removing the excess phosphate in the pool will help curb the growth of algae.

Does pool clarifier remove phosphates?

Your water is cloudy or not as clear as it should be normally, or it even shows the presence of phosphates after testing and you have applied a clarifier.

What you successfully did was to make the pool clearer. A clarifier does not remove phosphates in any way. If you want to remove the phosphate in your pool, you can shock it or get a phosphate remover to do the perfect job.

Where do phosphates in pool water come from?

Phosphates get into the pool in several ways. Most of the time, you are not even aware that you are shocking phosphates indirectly into the water.

Phosphates could get into your pool through chemicals, dried leaves, dead animals, hair, etc. There are so many chemicals we apply daily to our pools that contain phosphoric acid. When you apply these chemicals to the pool, they solve the problems you are trying to solve and indirectly add phosphates to the pool.

It could also get into your pool through the tap water you used to get your pool filled. Many plumbers or tap owners use phosphoric acid to maintain their pools. Phosphates get into the pool through organics.

Let us assume you have grass around the pool area, and you have used fertilizers that have little phosphates on the grass. It is  obvious that you did not apply the fertilizer directly to the pool, but some factors like rain can make these chemicals flow into the pool, thereby increasing the phosphate.

Does rainwater contain phosphates?

Almost all organic elements on earth contain phosphate. Examples are hair, skin, water, and soil.

Rainwater is not excluded from the list. Phosphoric acid, which makes up phosphate, can be found in rainwater.

How do I control phosphates in my pool?

Phosphate should always be tested for, especially during the heat and summer, and also in springtime when you open your pool and also when you close the pool to be sure that the water remains clean and crystal clear. Your phosphate level should not be more than 200 ppm. If so, then you should definitely use a phosphate remover to maintain clear water.
