The color of your pool water can be an indication of its quality. However, there are several factors other than dirt and pollution that can cause it to be blue. In this article, we will discuss some of the possible reasons that your pool water could be tinted blue.

Algae Bloom

One of the first things you will notice if you visit a pool deck is the presence of green algae blooms. These algal blooms can clog the grates on the floor, getting in the way of efficient water circulation and making your pool water appear darker in color. There are numerous species of algae that can swim in your pool, some of which are extremely aggressive and can rapidly multiply, covering the surface of the water in short order. This can lead to an undesirable appearance as well as pose a health threat to you and your family. Preventing algae bloom is certainly within your control, and easy to do. Just make sure that the water is always clean and free of any excess nutrients. You can also purchase an algae bloom filter that will trap organic debris before it reaches the pool.

Municipal Treatment Plants

Municipal treatment plants (MTPs) are a common cause of bright blue pool water. The MTPs use chlorine to disinfect the water that passes through their system. While this might be effective in preventing disease, too much chlorine can cause the water to take on a bluish tint. These are perfect storms of chlorine and algae that can quickly turn your pool water a disconcerting blue color. The presence of chlorine in your pool also makes it highly susceptible to algae blooms and bacterial growth. If you are unlucky enough to have an MTP near your pool, be rest assured that your water will be clear of any visible algae, but that it still has all the harmful bacteria behind the scenes. Some communities have banned or restricted the use of MTPs near their pool facilities, so you will need to find out what is the local policy regarding this issue before you make any drastic changes.

Radiation From The Sun

This one may come as a bit of a shock, but the sun is one of the major causes of your pool water becoming tinted blue. If you are not careful, prolonged exposure to direct sunlight can cause the water to take on a bluish tinge. The amount of radiation that the sun emits is enough to damage living cells and create free radicals that are extremely dangerous and can cause serious health issues. If you fear that this is a problem for you, you can always shield yourself from direct sunlight during the day by covering up with sun shades or using sun protection films.

High Salt Levels

Some types of salt can cause your pool water to become tinted blue. This is mostly the result of the chemicals that they contain, which can damage the surface of the water. The most reliable resource for finding the right salt for your needs is the grocery store’s fine-selection section. You should be able to find almost any type of salt that you need there, and if not, ask the store’s staff for assistance so that you can make the right choice for your pool needs.

Tricky Water

There is also the possibility that your pool water could be tinted blue due to the presence of minerals or chemicals in it that give it a bluish tinge. This is sometimes referred to as tricky or odd water. The exact cause of this condition is not always known, and in some cases, it is even difficult to pinpoint. However, when it is present, it will inevitably affect the quality of your pool water. The factors that cause this condition include the presence of iron, magnesium, or calcium. It can also be a byproduct of extreme pH levels or extremely high or low water temperatures. Regardless of the cause, this is an issue that you need to be aware of and ensure that your pool is safe from when you swim in it to when you clean it after use.

Foul Debris In The Pool

Whether by accident or design, it is possible for foreign objects to find their way into your pool. This can happen whether you have an in-ground pool or a simple garden hose connected to your faucet. Naturally, you will have to clean your pool thoroughly after each use, regardless of whether or not it was littered with debris before you entered the water. In some cases, the debris can be so aggravating that you will have to replace large amounts of water. Sometimes, this means that you will have to haul away a large amount of water from the community’s system if they don’t provide any type of filtration system in place.

The truth is that it’s not always easy to determine the exact cause of your pool water becoming tinted blue. The above are some of the more common reasons that your pool might have this issue, and they all contribute in one way or another. If you are looking for a pool that will remain blue-tinted, then make sure that you find one that is constructed using only pure materials and has been treated with chemicals that are known for removing algae and bacteria. While it is certainly within your control to maintain a clear pool, you also need to make sure that all of the above are taken care of in order to achieve this goal.
