How to Make the Water in Your Pool Blue

When you think of a pool, it’s not too much of a stretch to assume blue-hued water is what comes to mind. It’s actually something that occurs due to a combination of the sun’s light and the chemicals used to keep the water clear and healthy. However, there are times when the water in your swimming pool may not be blue for various reasons. If this is a concern for you, here’s what you can do to make your pool’s water blue.

Understand Why Pool Water May No Longer Be Blue

If your San Diego swimming pool isn’t covered, it can become contaminated by rainwater or runoff from nearby soil and change color for this reason. Your pool’s water may also no longer be blue because of algae, which actually turns the water green. Another possible reason for discolored pool water is an imbalance of chemicals. If this happens, microbes and other substances can leave you with unsightly pool water.

Shock Your Pool

If excess algae is the problem, an effective way to make your pool’s water blue again is to shock it. Follow the treatment instructions and add what’s recommended based on your pool’s size and water volume. Once you shock your pool, the algae will gradually disappear, and your water will turn blue again.

Use a Pool Vacuum

Pool water may also become discolored if dead algae and other debris settle to the bottom. If this is an issue with your pool, use a pool vac to clean the bottom properly and thoroughly. After you do this, the water should once again turn back to the blue shade associated with clean, clear pool water.

Test Your Pool’s Water

If you suspect the problem is a chemical imbalance, use a test kit to check your pool’s water. The results from the test will determine what steps you’ll need to take to restore the balance. For instance, if the pH is too low, alkaline salts should be added. Conversely, chlorine needs to be added if the pH is excessively high.

Check the Filter

Your pool’s water may be cloudy or discolored if the filter is clogged or not working as expected. The filter should be checked as part of routine maintenance anyway, but it’s also time to check it if the pool water test doesn’t show any chemical imbalances.

Develop a Regular Maintenance Routine

You’ll be more likely to have blue pool water that’s free of excess debris, algae, or similar materials if it’s maintained regularly. Typically, this means a routine inspection and cleaning every 1–2 weeks while you’re using your pool. Also, do a more thorough cleaning at least once a month when frequently enjoying your pool.

Cover Your Pool when Not Using It

Lastly, reduce the risk of unwanted materials getting into your pool and affecting the water color with a pool cover. This is also an effective way to maintain your pool’s water level, which further keeps the chemicals you regularly add correctly balanced.
