How To Lower Phosphates In Swimming Pool – High Remover (2021)

Water is an essential compound on the planet.

Without water, there would be no life on the planet.

However, do you know that water usually consists of a lot more elements than Hydrogen and Oxygen?

Don’t worry, if you don’t.

Water is a wonderful compound.

You can mix almost any element with it.

You will be surprised to know that majority of the elements in the periodic table, dissolve in water.

One of those elements is phosphor.

It even has compound forms, which are known as phosphates.

Phosphates are commonly found in water – Phosphates in pool.

There is no water in the world that does not contain phosphates in it.

Of course, some water needs to be treated against phosphates.

If you treat your swimming pool water with chemicals such as chlorine, then there are high chances of phosphates being found in the water.

Anything above safe phosphate levels is harmful.

There are instances when the phosphate levels might increase above the limit.

Managing the phosphates in pool can be challenging.

Don’t worry.

We have got it covered.

Let us discuss phosphate removers and other methods pool owners can use to reduce a high phosphate level in pool water.

You can even eliminate it.

Phosphates in pool

During its life cycle, algae stores phosphates, and when it dies it sinks to the bottom of the water body. All the phosphates in the pool are then absorbed back into the water and the cycle resumes. Not to mention, new sources of algae continue to get added to the water body. This is called nutrient pollution and is one of the worst environmental offenders. Do You Need to Remove Them from Your Pool?

Phosphates in pool – Testing

The first step is to know the present phosphate levels in the pool water.

Without knowing this, you cannot take appropriate steps to maintain the level of phosphates in your pool.

You can easily test the phosphate levels in the pool water by using test kits available on the market.

But, not every test kit contains a test for phosphate levels in it.

It is most likely that you have to use a phosphate test kit to test the phosphate levels.

You need to look for the following factors in any kit for testing for phosphates in pool water.

  • It must be of a reputable brand
  • It should be in your budget
  • It should be easy to use a phosphate test kit
  • Select kits that offer results within minutes
  • Accuracy is important
  • It must be able to do other tests as well

Make sure that you follow the procedure of the kit properly when testing for phosphates.

Keep the chemicals under control

One of the main reasons behind the high phosphate levels in pool water is the imbalance of chemicals.

Pool owners use different types of chemical products to kill bacteria, as well as algae growth.

However, in this process, some tend to use excessive chemicals in their swimming pool.

This excessive use of chemicals usually leads to an imbalance of the level of chlorine, alkalinity as well as the PH of the pool water.

Thus, you need to make sure that the level of other properties of the pool water is balanced.

You can easily check the level of these properties by using pool testing kits.

Make sure that you are using chemicals in a limited amount.

It is also recommended to take proper steps to balance PH, alkalinity, chlorine, and others in the water.

What removes phosphates from pool water?

Use a pool phosphate remover

Just like there are chemicals to increase the level of chlorine, there are products on the market that can reduce or remove phosphates in the pool.

You can always select these products as they are highly effective against phosphates.

However, it is recommended to use a phosphate remover as your last option as they do more harm than good to the water.


A phosphate remover eliminates phosphates from the water, which disrupts the balance of chemicals in the water.

Phosphate removers essentially use a metal element called lanthanum. It is classified as a rare earth metal. There have been studies that show species like freshwater crustaceans are especially sensitive to lanthanum. In other words, it is known to have a toxic impact on at least one kind of marine life.

Techniques/Tips to improve phosphates in pool

We have discussed some basic steps that you can take to reduce phosphates.

However, they may not be sufficient for your pool.

That’s why we brought you some additional tips that could help remove phosphates more easily.

1. Use skimmer baskets

Skimmer baskets are wonderful filters for swimming pools.

They are designed specifically to filter out the debris and algae growth in the pool.

Now, you may wonder how debris like leaves can affect the level of phosphates?

Well, organic residue, like leaves, is a great source of food for algae, which results in algae blooms on such material.

Thus, if you have a large amount of debris in your pool, then it is likely to promote algae growth and not prevent algae from taking root.

You also need to make sure that you select the right type of pool skimmer basket.

There are various types of basket kits available on the market.

You need to look for the following things to select the best basket.

  • The quality of the material should be high

How to lower phosphates in pool – Frequently Asked Questions

What causes phosphates in the swimming pool?

There are various factors behind an increase of phosphate in the pool.

However, here are the most common reasons behind it.

  • Lots of organic debris in your pool.

Yes, no matter the size or shape.

Even small organic debris can change the level of phosphate content.

  • The second reason behind the high level of phosphate is an imbalance of chemicals.

You need to make sure that the chemicals in the pool are in balance.

Why maintain phosphate in the pool?

Phosphate is a major source of food for algae.

Thus, if you have a high level of phosphate in the pool, then it is likely that the growth of algae will be fast.

Now, we have been discussing maintaining phosphate.

If phosphate leads to the growth of algae, then should you not completely remove it?

Well, you are not wrong.

Removing phosphate can surely eliminate algae in the pool.

However, that will give rise to various other problems.

What other problems?

Well, have you heard of cloudy water?

If yes, then you might know how difficult it is to handle.

For those who do not know about cloudy water: It is a state of water, where you observe the hazy color of the water as well as some foam on the surface.

Now, why does this occur?

Well, it is basically because of a lack of compounds in the water.

Everything in the universe works in balance.

The same goes for water.

Only water with balanced compounds is considered perfect for swimming pools.

Thus, it is highly recommended to have a small level of phosphate in the water of the pool, but not enough to overly promote algae growth.
