Can a pool be green but have high chlorine?
A pool can be green but have high chlorine levels when the chemicals are unbalanced. Too much combined chlorine, high pH levels and also high cyanuric acid (CYA) levels can cause the chlorine to be ineffective with both situations potentially causing algae to grow.
What makes a pool turn green and how to fix it?
What Makes a Pool Turn Green and How Do I Fix It? 1 Not Enough Chlorine 2 Too Much Cyanuric Acid (CYA) 3 High pH Level 4 High Phosphate Level 5 Not Enough Filtration
What happens if you put too much chlorine in a pool?
Adding too much chlorine can increase the pH levels, but other chemicals can also increase the acidity of the pool water. Furthermore, the more acidic the water becomes, the less effective that chlorine is. For this reason, the pH of the pool water is also very important to check.
What should the chlorine level be in a pool to prevent algae?
Not Enough Chlorine Algae growth turns a pool green, and algae grows when pool water lacks chlorine. A pool’s free chlorine level should be between two and four parts per million.

How much chlorine to add to pool if it is green?
Light Green or Teal Pool Water: This means there's a low amount of algae in your water and you won't have to use a hefty amount of chlorine shock. In this case, you should double shock your swimming pool water. To double shock, you will need to add 2 pounds for every 10,000 gallons of water.

Why did my pool water turn green after adding chlorine?
Pools can immediately turn green after shocking when they have metals like copper in the water. These metals oxidise when exposed to high levels of chlorine which makes the pool water turn green. Adding a metal control product such as Zodiac Metal Remover will help to restore the pool water.

What is a CYA pool?
Cyanuric Acid (stabilizer, conditioner, CYA) is essentially sunblock for chlorine. Too little of CYA and the chlorine burns off pretty quickly which can lead to a green pool. However, too much of it and it basically turns into handcuffs for chlorine and not allow it to work properly in sanitizing your water.
How long should a pool filter run?
Generally speaking we need the filter to be running 8-10 hours a day during the summer time mainly because to the higher temperatures and higher bathing loads. Both are responsible for eating up your available chlorine which can turn into a green pool. In the winter time you can get a way with 4-6 hours.
What is the best PH level for chlorine?
High PH: Chlorine works better at a lower PH. The recommended PH level is between 7.2-7.8 with 7.5 being ideal. Chlorine works more effectively at 7.2 than it does at 7.8 even though a PH at either of those two are considered acceptable. So when your pool's PH is at 8.0, 8.2 and above it's not working as efficiently.
Is liquid chlorine good for sanitizing water?
I'm a big advocate for liquid chlorine because you are not adding CYA when you sanitize your water. Stabilized chlorine is great for certain applications, but your standard liquid chlorine is the best for daily/weekly sanitizing. So there you have it.

How to check CYA level in pool?
Find out your pool’s CYA level by taking a water sample to a pool and spa store so they can properly test it. CYA is hard to remove from water. Often the only way to fix the problem is to partially drain the pool and refill it with fresh water. Going forward, watch how many chlorine pucks you add to your pool, because they also contain CYA.
What is CYA in pool water?
Cyanuric acid (CYA) is a water conditioner and stabilizer that prevents chlorine from degrading in sunlight. The CYA level in pool water should be between 30 and 50 parts per million. Any higher means trouble. “Once you get around 80 to 100 parts per million or more, the chlorine can no longer do its job effectively,” explains Steve Goodale, a writer and technical specialist who reaches millions of pool and spa owners each year through his Swimming Pool Steve resource blog and YouTube channel.
What is phosphate in a pool?

Why is my pool a buffet for algae?
Phosphates in the water can be a food source for algae, so if the level of phosphates in your pool water (usually included in a basic pool water chemistry test) is too high, your pool is essentially a buffet for algae. The answer to this is balancing the level of chlorine or another sanitizer.
Why is chlorine used in drinking water?
Chlorine is used to purify water, including most municipal drinking water, because it will kill nearly any organism that could be harmful to humans. When the levels are properly balanced, chlorine will keep the algae at bay, but the water will slowly begin to turn green as the algae take over if there’s not enough.
What happens if the pH is too high?
The goal is to keep the pool water reasonably neutral, with a pH of around 7.3 to 7.6. If the pH becomes too high (over 7.8), it prevents the chlorine from doing its job.

Is Chlorine to Blame?
Whenever the discussion around green hair in the pool arises, chlorine is always the first thing to get called out. However, chlorine is only half of the green-hair equation, here. The real tint-changer behind it all is copper. And copper not only exists in pool water but tap water too (though rarely in high enough concentrations to affect your hair). Copper is the actual agent that’s creating the reaction that causes your hair to turn green. But the thing is, it rarely happens outside of the pool for one very important reason. And that reason is, you guessed it – chlorine. Chlorine and copper bond together to form a film that sticks to the proteins in your hair, coating each strand and making it that much easier for it to turn green.
