4 Reasons For Cloudy Pool or Spa Water and How to Clear It

Are you wondering why your pool or spa water might appear cloudy? Various things may cause this issue; however, there are also many things you can do to resolve it in no time! Below, we’ll provide you with exactly what you need to know about why this might be happening and what you can do to fix it.

Why Is My Pool Water Cloudy, And How Can I Fix It?

Clearing cloudy pool or spa water starts with figuring out the root of the cause. By knowing what’s causing the issue, you can ensure that you’re fixing it long-term. Here are some possible reasons why your water might not look the way it should.

Reason #1: The Water Balance Is Off

One of the main causes of cloudy water is improper chemical balance. When the pH, alkalinity or calcium hardness levels aren’t within the recommended range, the water isn’t in a healthy state. The ideal pH levels should be between 7.2 to 7.6. If it’s not within this range, it means the water is too acidic or too alkaline. This can lead to skin irritation and potentially damage the working parts of your pool or spa if left untreated. Too much chlorine can also lead to murkiness. The ideal amount of chlorine in pools should be at least 1 ppm, while it should be at least 3 ppm for swim spas.

What to Do: Use a testing kit or testing strips regularly to monitor the chemical balance in your pool or swim spa. You should add the necessary chemicals to get the balance back on track if it’s off. You can also ask your local pool retailer for help when it comes to choosing the right chemicals to keep at home.

Reason #2: The Filter Has Problems

If your pool or swim spa’s filter system isn’t in top shape, it won’t be able to do its main job of helping to keep the water crystal clear. Once this happens, the water in your pool or spa can get stagnant and dirty, manifesting as cloudiness.

What to Do: Check the filtration system regularly to ensure it’s in the best working condition. There should be no build-up that can cause clogging. If you find that the filter is no longer working as it should, then a repair or a replacement might be in order.

Reason #3: There Are Contaminants From Swimmers

Cloudy water can also be caused by excess particles from people who use the pool or swim spa. Sunscreens and oils are the most common examples. However, other particles such as make-up, deodorant, cream, perfume, etc., can also count as contaminants. When combined, these chemicals and particles can affect the overall balance of the water and, of course, how it looks.

What to Do: Pool clarifiers can be a great fix for this particular issue. It works as a coagulant, gathering together small particles and substances. This way, it’s easier for the filtration system to capture them. Just note that pool clarifiers aren’t meant to be used all season long as a solution, as it’s important to still find the root of the problem.

Reason #4: Environmental Influences Affecting Water Quality

When there are leaves, twigs, flowers, and pollen in your pool or swim spa, they can affect the water’s quality and appearance. As a result, cloudiness can happen, especially when the water circulation isn’t working as it should because there’s an imbalance.

What to Do: Set a regular cleaning schedule for your pool or swim spa. This includes skimming, vacuuming the bottom, scrubbing, and backwashing. Investing in a high-quality swim spa cover is also a good idea. It can help save you a lot of time and effort spent cleaning.

Cloudy water is bound to happen from time to time when you own a pool or a swim spa. But by figuring out exactly what’s causing it, you can apply an easy fix as soon as you spot it. For more information about choosing the perfect swim spa for your home, download our free buyer’s guide.
