Why do we need to test for phosphates in our pool?

Phosphates, primarily consisting of organic material, can serve as a nutrient source for algae, promoting their growth in your pool and leading to water cloudiness.

Algae requires sunlight, water, oxygen, and nutrients like nitrates and phosphates in order to thrive.

This is why a swimming pool can be the perfect environment for algae to bloom!

High levels of phosphate also deplete chlorine rapidly, further complicating the eradication of algae and the maintenance of a clean pool.

It is possible to consider that the chlorinator is not generating sufficient chlorine, but in reality, the chlorine being produced is being used up at a faster rate than it can be manufactured.

How do phosphates get into your pool? Your pool is in an open area exposed to sun, water from rain, air, dust, and food for algae that may be introduced in many ways. Phosphates are present in your landscaping and fertilizer materials, and can be introduced by wind and water run-off, by means of rain or your own garden watering efforts. The phosphates can be deposited from environmental debris that enter the pool in the form of leaves, dust and bird droppings.

Ideally, you want zero phosphates in your water. In order to rid phosphates from your pool, you will need to use a chemical to remove them, such as a Lanthanum based product.

Along with using a phosphate remover, you need to remove debris such as leaves, sticks, and bugs on a regular basis. Emptying out skimmer baskets on regularly will also get rid of the debris quicker. It will also improve the water circulation.

Take your water to be professionally tested at your local pool shop, and if you have phosphates in your water, be sure to treat them as per instructions.
