How to Fix Blue Water

Swimming pools are a great way to relax and cool off during a scorching summer day, but when you dive into your pool only to find that the water has turned blue, it can be quite alarming.

How to Fix Blue Water

Cloudy or blue water in your pool means there is something wrong with the water chemistry, and it needs attention before it worsens. This may seem daunting, but with the right tips and tricks, you will be able to clear your pool before you know it. In this guide, we will walk you through the steps on how to fix blue water in your pool.

Can You Fix Blue Water?

If you’ve ever seen blue water coming from your tap, you may wonder if there’s any way to fix it. While it can be alarming at first, there are several reasons your water may turn blue, many of which are harmless. For example, if you’re using a copper product, such as a pool algaecide, it could react with your water to create a blue tint. Similarly, if your plumbing has copper pipes, the inert metal can occasionally leach into your water, coloring it blue. In most cases, blue water is nothing to worry about – but if you’re concerned, it’s always a good idea to have your water tested to rule out any potential problems.

Why Should You Fix Blue Water?

Bluewater is a natural wonder integral to our oceans’ beauty and health. Unfortunately, we’re losing faster than we’re gaining it due to pollution and other human activities. If we want to continue enjoying the vibrant colors of the sea, we need to make a concerted effort to fix blue water.

By doing so, we can give marine life the habitat they need to thrive while preserving a vital resource that brings joy to millions of people worldwide. Whether swimming in the ocean, surfing, or simply admiring its beauty from afar, blue water deserves our attention and care. Join the movement to fix blue water and help create a brighter future for marine ecosystems and humanity.

How to Fix Blue Water: Tips and Tricks

1. Identify the Cause of the Problem

The first step you should take when faced with blue water in your pool is to identify the cause of the problem. The most common cause of blue water is the presence of copper in the pool water. Copper can leach into the water from copper pipes, heaters, and algaecides containing copper. Another common culprit is high pH levels, which can cause the water to turn blue or green.

2. Test the Water

Once you have identified the cause of the problem, it is time to test the water. Test the pH, chlorine levels, and alkalinity using a reliable pool testing kit. You should also test for copper using a test kit specifically designed for that. Once you know the levels, you should balance the chemicals according to the results of your tests.

3. Use the Right Treatment

The next step is to choose the right treatment for your pool water. If copper causes a blue color, you should use a chelating agent designed to remove copper from pool water. If the high pH is the reason behind the blue water, you should add muriatic acid or sodium bisulfate to lower the pH. Always follow the instructions carefully and avoid overdoing it, which can worsen the situation.

4. Shock Your Pool

If your pool water is cloudy or blue due to algae content, shock your pool. Shocking your pool means adding a large dose of chlorine to the water to kill any algae that may have developed. You may want to brush the walls and floor of the pool before shocking, and always follow the product’s instructions carefully. After shocking, allow the pool to sit for a while before using it.

5. Use a Clarifier

Using a pool clarifier can also help to clear up blue water. A clarifier works by binding small particles together, making them easier to filter out or sink to the bottom of the pool. This will not solve the underlying issue causing the blue water, but it can help to quickly improve the overall appearance of your pool.

6. Check Your Pool Equipment

Sometimes, blue water can be caused by an issue with your pool equipment, such as a malfunctioning filter or pump. Regularly check and maintain all of your pool equipment to ensure proper functioning and prevent any potential issues that may lead to blue water. Address any equipment problems as soon as possible to avoid further complications.

7. Prevention is Better than Cure

Prevention is always better than cure. Regular pool maintenance can help keep the water chemistry in check — keeping your pool clean and balanced can prevent blue or cloudy water. Remember to check the chlorine levels regularly and add more if necessary. You may also want to shock your pool periodically to keep chlorine levels in check.

5 Considerations Things When You Need to Fix Blue Water

1. Identify the Source of the Problem

The first step in fixing blue water is to identify the source of the problem. This can be done by testing your water for contaminants such as bacteria, lead, and nitrates. Once you have identified the source of the problem, you can take steps to address it. For example, if bacteria are present in your water, you may need to install a filtration system or use a chemical treatment to kill off harmful organisms.

2. Test Your Water Regularly

Once you have identified and addressed the source of your blue water, it is important to test your water regularly to ensure the problem does not return. Regular testing will also allow you to monitor any changes in your water quality over time and take corrective action if necessary.

3. Invest in a Water Softener

If hard water is causing your blue water issues, investing in a water softener can help reduce scale buildup and improve the quality of your drinking water. Water softeners work by removing calcium and magnesium ions from hard water, which helps reduce limescale buildup on pipes and fixtures.

4. Install an Iron Filter

If iron is present in your drinking water, installing an iron filter can help reduce its presence and improve the taste and odor of your drinking water. Iron filters use oxygenation or oxidation processes that convert dissolved iron into harmless particles that can be filtered out before entering your home’s plumbing system.

5. Consider Reverse Osmosis

Reverse osmosis (RO) systems are highly effective at removing impurities from drinking water, including sediment, chlorine, lead, arsenic, fluoride, heavy metals, and other contaminants that may be causing blue-green staining in sinks or tubs. RO systems typically have several stages, including filtering out large particles before passing through a semi-permeable membrane where smaller particles are removed from the drinking water supply.

Benefits of Fixing Blue Water

Water is an essential element of life, and we must make every effort to ensure it is clean and safe for consumption. Fixing blue water, or water that appears to have a blue tint, is an important step towards this goal.

Not only does it improve the aesthetic of water, but it also enhances the quality by indicating a lower presence of contaminants. Clear, clean water can also positively affect mental well-being and encourage individuals to appreciate nature. By addressing blue water, we are not only taking care of ourselves, but we are also preserving our environment for future generations.

Clear Clean Water Can Also Positively Affect

Some Common Mistakes People Make When Trying to Fix Blue Water

Isn’t it frustrating when you turn on your tap, and all that comes out is blue instead of clear water? It’s not uncommon to panic and immediately start searching for solutions, but be careful not to fall into some common traps. One of the biggest mistakes people make is adding bleach or chlorine to clear up the blue hue.

While this may work temporarily, it can damage your plumbing and make the problem worse in the long run. Another mistake is ignoring the issue and hoping it goes away independently. Unfortunately, blue water can indicate serious problems like copper or lead contamination, so it’s important to address it head-on. Don’t let the blue water blues get you down, but approach the problem carefully and thoughtfully.


Fixing blue water in a swimming pool can be quite a task, but following these tips and tricks can maintain the water chemistry and keep the water crystal clear. Always remember to test the water and identify the root cause of the problem before taking any action. Use the right treatment, follow the instructions on the package carefully, and always maintain the pool’s cleanliness to avoid any future problems. With a little effort, you can enjoy crystal-clear water in your pool all summer long. Thanks for reading our post about how to fix blue water.
