Reasons Why Your Pool Goes Green

It can be a big challenge for swimming pool owners to keep their pool water clear and blue throughout the summer. Oftentimes water can go from sparkling blue to pond-like green overnight. Luckily, it isn’t difficult to figure out why your swimming pool might have turned green.

Many pool owners don’t want to use too much chlorine, but using too little chlorine can result in a green pool. Be sure to follow specifications for your size pool and keep a regular chlorine schedule. If you are concerned about swimmers getting too much chlorine, try to time chlorination for times when the pool will not be in use for a few hours. This is a good idea if you have small children in your pool who may accidentally swallow water.

Check your water’s pH regularly and be sure you are adding the right amount of chemicals. This attentiveness and regular chlorination will help prevent a green pool. It is particularly important to monitor the pH of your pool when it has rained. Pool owners tend to think of rain as a good thing and a way to warm and fill up the pool, but rain water has a different pH from the water in your swimming pool. Too much rain water, without chemicals to adjust it back to normal, can cause your pool to turn green.

If your pool has already turned green, you may need to “shock” your pool. Shocking the swimming pool means that you add a large amount of chlorine to the water in order to get the color back to normal. Always shock your pool at a time when it will not be used for several hours, the extra chlorine may bleach clothes and irritate skin and eyes.

Another reason your pool may turn green is because of lack of good water circulation. Algae tends to grow in a pool if the water is still for too long. This can cause a green “pond-like” look. Running the filter regularly should help to keep the water moving. Regular use will also help to keep your water moving.

If you use a cover on your pool in between uses, such as a solar cover to help warm the water, this can cause your pool to turn green. This happens because the pool will be closed up and the water won’t circulate as well. Try to avoid covering your pool during swimming season.

If your pool has turned green, it is especially important to get the water moving. Begin by brushing the bottom of your swimming pool manually and fishing out any leaves and bugs. Don’t be alarmed, this may cause the pool to look even greener at first. Stirring up the water and getting out debris will help the filter to do its job better. Next, begin running the pool filter 24 hours a day until the water color has returned to normal. Be sure to backwash your filter at least a couple times each day during this time to prevent it from getting clogged.

Keeping your pool from going green can be a challenge, especially to new pool owners, but with a little effort and detective work, it will be back to clear water in no time.
