Tips to Lower the Chlorine Level in Your Pool Stop Adding Chlorine and Start Swimming. Use the Sunshine. Heat the Pool Water. Dilute the Pool. Use Hydrogen Peroxide. Use a Chlorine Neutralizing Product. Try Sodium Thiosulfate.
Why is my free chlorine high?
Adding too much pool shock or putting too many chlorine tablets to the feeder can both result in very high levels of chlorine. Another common way to over-chlorinate a pool is to leave a liquid chlorine pump running all night – you’ll often come in the next day to discover a greenish-looking pool.
Does shock lower free chlorine?
Adding more free chlorine to the water, a process called superchlorination or shocking, reduces the chloramine level because free chlorine breaks the chemical bonds of the chloramine compounds, converting them to nitrogen gas.
What to do if total chlorine is higher than free chlorine?
If total chlorine is higher than free chlorine, there are contaminants in the pool. Subtract the free chlorine measurement from the total chlorine measurement to calculate the amount of combined chlorine (total – free = combined). If combined chlorine is higher than 0.5 ppm you should shock the pool.
What neutralizes chlorine?
Vitamin C is a newer chemical method for neutralizing chlorine. Two forms of vitamin C, ascorbic acid and sodium ascorbate, will neutralize chlorine.
How long does a non-chlorine shock last?
After NON-CHLORINE shock wait 10-15 minutes before entering. After chlorine shock it can take up to 24 hours to clear. Therefore it is recommended to use non-chlorine shock.
Can you add too much non-chlorine shock?
If too much is added, it can cause the overall pH level of the pool to drop for a sustained period, which you’ll then have to raise. Whereas, with a chlorinated shock, if you overdose the pool on it, all you have to do is wait a few extra hours for the sun to burn off the chlorine.
What is a safe free chlorine level?
The ideal level of free chlorine in the swimming pool is 2 to 4 ppm. 1 to 5 ppm is acceptable and 9 ppm is on the high side. 9 ppm would likely be safe to swim, but could be more of an irritant. Ideally, the level would be alllowed to come down to 5 ppm before swimmers are allowed to swim.
What is the difference between free chlorine and combined chlorine?
Free chlorine involves the amount of chlorine that’s able to sanitize contaminants, while combined chlorine refers to chlorine that has combined directly with the contaminants.
How do I know if I have chlorine lock?
The quickest way to determine if a chlorine lock is present is to perform a test for total chlorine and free chlorine. Total chlorine is a measure of all the chlorine in the water and free chlorine is the chlorine that actually sanitizes the water. The two results should equal each other under normal conditions.
How do you beat chlorine lock?
Another way to break chlorine lock is to shock the pool with a non-chlorine shock. The non-chlorine shock will oxidize the chlorine in the swimming pool. Non-chlorine shock oxidizes the water, restoring the balance and making it cleaner. To break chlorine lock with shock, breakpoint chlorination is being done.
Should free chlorine equal total chlorine?
You want to make sure your free chlorine levels stay in check. For example, if your free chlorine levels and total chlorine levels are the same, then there’s no combined (or used chlorine) in your water. To make sure your pool is sanitized, your free chlorine should remain higher than your combined chlorine.
Should I test for free chlorine or total chlorine?
If the total chlorine level is higher than the free chlorine level, the difference of the two is the combined chlorine level. In order for your pool to be properly sanitized, the free chlorine level must remain higher than the combined chlorine level. This is why it’s so important to test your pool water regularly.
How do you get rid of chlorine naturally?
Yes, boiling water for 15 minutes is one way to release all the chlorine from tap water. At room temperature, chlorine gas weighs less than air and will naturally evaporate off without boiling. Heating up water to a boil will speed up the chlorine removal process.
How do you make chlorine neutralizer?
Directions: Mix 1/2 tsp sodium ascorbate with 4 ounces of distilled water. Use within 24 hours. (The solution breaks down and looses effectiveness after 24 hours.) Use: Generously spray After Swim Chlorine Neutralizing Spray all over immediately after swimming.
How do you remove chlorine from swimming?
Simply showering with soap and shampoo after you get of the pool will go a long way, too, toward getting most of the chlorine out. You can also mix a small bit of Vitamin C crystals with your body wash or shampoo to create your own swim shampoo and wash.
Does non chlorine shock raise free chlorine?
It uses the power of “active oxygen” to destroy contaminants in pool and spa water. This eases the load of your regular FAC residual, allowing that chlorine to stay effective longer. That said, it should be noted that non-chlorine shocks don’t kill algae, or raise the chlorine level.
Does non chlorine shock raise pH?
For many of the reasons outlined in point 2, Non Chlorine Shock can help improve water clarity fast. If you have milky or cloudy hot tub water but your chlorine levels, PH and alkalinity are ok then Non Chlorine Shock will oxidise the products causing this and help restore your water to crystal clear.
