Why Does Pool Water Turn Green?
While there any many reasons why your pool would turn green, most of the time it is due to your pool pump not working and filtering the water. We also suggest you look how to clean a pool filter. There have been many stories of people going on holiday and their pumps dying, and then people come to fix the pump without turning it back on.
We have also heard pools turning green after rain but we think that might be because water is running off into the pool. Another issue is your Levels may be incorrect or may need adjusting.
How To Clean Green Pool Water

Being one step ahead of algae is crucial because as algae grow, chlorine must work harder to keep your pool clean. But don’t worry. You have solutions that will keep your water blue and clear from those uninvited green guests (that have no problem overstaying their welcome in your beautiful pool.) Consider using a preventative algaecide weekly if your pool is prone to algae or when the temperature increases during the peak of summer.
The Lack Of Free Chlorine Matters!
When your pool has lots of algae, your FC (free chlorine) level is nearly 0. Without any FC, generally speaking a pool is unsafe to swim in. This is critical to Why Does Pool Water Turn Green! Its not exactly the algae that causes the danger in the water, its actually the other things that end up in the water.
Chlorine is what keeps the pool sparkling clean. The algae will be essentially eating the chlorine. Without FC, and with all that algae, what ends up happening is certain bacteria have the potential to thrive.
If you didn’t know, various animals will come and swim, drink and also nard in the water.
So while you might not mind the Algae, you may mind the fresh duck fecal matter that has been sitting on top of the water for the past week! While you are not guarantied to get sick from swimming in a pool with algae, it really isn’t a good idea. I mean you wouldn’t swim in a swap would you?
Why Can I Swim In A Lake But Not A Green Pool?
People often wonder if its safe to swim in a green pool, Why Does Pool Water Turn Green? Lakes and rivers do get algae, but they are more of an self sustaining ecosystem. Lake will have a fine balance of bacteria, much greater water volumes, and filtration going on by the plant life. There are issues with bacteria in lakes too, many beaches will shut down on really hot days if the bacteria takes off, it’s just much more likely to happen in the small space of a pool.
This is why it is advised you don’t put your head underwater when swimming in lakes. With a green pool, you end up with a much higher chance of getting an illness (especially a throat, eye or ear infection).
So The Verdict? Why Does Pool Water Turn Green?
Well, in the end its up to you. But I wouldn’t put the safety of my children or family in harms way because I forgot to clean the pool.
As said before this is NOT the same as swimming in a river or lake as they are a natural ecosystem and it doesn’t matter if they are green (Most of the time). So how to get your pool blue? Remember if its GREEN, We suggest using CLOROX Pool & Spa Green Algae Eliminator to shock the pool correctly!!
