Iron is a naturally occurring element present in water. However, despite the fact that it is a required nutrient for plants and algae, it can accumulate in toxic amounts in certain circumstances. That is why it is important to know the signs of excessive iron in water, especially since some water bodies are more prone to accumulating this element than others.

Causes Of Iron In Pool Water
Excessive iron in pool water can be caused by a number of factors. The most common one is iron pollution. This is something that can occur when there is excessive iron in soil, dust, or food (particularly meat and seafood) that washes down the drain and into the pool. Another major source of iron pollution are car fumes, especially gasoline. These chemicals dissolve in water and release free iron into the water source. Also, chemicals like pesticides and herbicides which are used on nearby agricultural lands can leach into nearby ponds, lakes, or oceans and create an unsightly orange bloom that will eventually lead to the death of many aquatic life forms.
How Do You Test For Iron?
The easiest way to test for iron in pool water is with a ferrotest strip. These are waterproof test strips that contain chemicals which change color when they come into contact with iron. Most pools will have a water quality sensor which will send you a visual alert if the iron level is above the allowed limit. It is also advisable to have water tested professionally at least once a year.
Do You Need To Test For Other Chemicals In Pool Water?
It is also a good idea to test for other chemicals in pool water. For instance, you should check for ammonia, nitrates, and phosphates, as well as test for pH levels (acidity or alkalinity). Having these chemicals analysed by a pool service will help you get a better idea of what is causing the algae and fish deaths in your pool. It can also be helpful to know how much bromide or chlorine your pool has accumulated. These are often the consequences of improper chlorination or lime softening which can cause algae blooms. Knowing how much of these chemicals are in your pool will help you figure out how to get rid of them.
Sometimes, the source of the pollution cannot be pinpointed. In these cases, the only option is to filter the pool. In some situations, this can be a temporary solution but it is always better to install a pool filter which can remove all the harmful elements from the water source.
Warning Signs Of Iron In Pool Water
If you discover that your pool water is polluted with iron, then it is already too late to do anything about it. However, you need to keep an eye out for the warning signs which will indicate that iron is becoming a problem. Some of these signs are listed below.
- An excessive amount of algae in your pool;
- A slimy sheen on your pool surfaces;
- Fish or other aquatic life dying off in large amounts;
- Your pool water becoming murky;
- Pools that do not settle within 15 minutes of being stirred (floating pools).
How Do You Remove The Algae?
Once you have found out that your pool is affected by algae, then the only solution is to get rid of it. Fortunately, this is a task that is quite simple. All you need to do is take out the algae using a water jet skimmer. This will not only get rid of the algae but it will also help cleanse your pool water.
The skimmer will attach to the side of your pool and will allow you to direct the stream of water at the surface of the pool. As the water hits the surface, it will disperse the algae and dirt which has accumulated at the bottom of the pool. If you are not confident in doing this by yourself, then it is advisable to call in an expert who can help remove all the algae for you.
Dangers Of Iron In Swimming Pools
It is important to keep in mind that iron in swimming pools is extremely dangerous. Even in small amounts, this element can cause irritation to the skin and eyes, as well as damage to the liver. If you swim frequently in polluted water, then you will put yourself at risk of contracting blood diseases like anemia or leukemia. This is why it is important to test for iron in pools and take appropriate action if it is found in excessive amounts.
