Chlorine naturally dissipates into the air and out of your pool water when exposed to sunlight. The process usually takes less than a week. If you plan on using pool water to irrigate your trees, don't add any more chlorine to your pool. After four or five days, test the water.
Simply stop adding chlorine to your uncovered pool and wait. Sunlight will help to naturally dissipate the chlorine within 10 days. During that time, use a swimming pool test kit to measure chlorine. Chemically dechlorinate the pool water.
Dechlorinator should work in less than five minutes. This does assume you are following directions properly and using the correct amount of dechlorinator. You must check the packaging of the dechlorinator you purchase. There are several different kinds out there, and some will work fast while others take longer.
Does Leaving Water out Remove Chlorine? As a matter of fact, allowing water to sit for a whole day is the safest way to dechlorinate it. Although it is the most time-consuming method, it is the best way to dechlorinate a large volume of water without the need for heat.
Generally after shocking your pool you should wait to swim at least 8-12 hours until chlorine levels come back to normal (1-3ppm). This is one of the few times that having a high chlorine level is a good thing. Always test your water before swimming again to make sure your chlorine levels are safe.
After Shocking Your Pool
It is safe to swim once your chlorine levels are around 5 ppm or after 24 hours. It is always best to test first!
BUT, if you have to shock your pool during the day in broad daylight, you can still swim after adding shock. It's recommended that you wait one hour after adding shock with the filter running, and then test the water to confirm the pH and chlorine are in the proper range before letting anyone enter the pool.
Dechlorination is the process of removing chlorine and chloramine from water. It is a necessary task each time you clean out your fish tank. Without the aid of dechlorinating substances, it takes about 24 hours for standing water to dechlorinate on its own.
Also, aeration helps chlorine evaporate, but chloramine will remain in water. Boiling your water for 15 to 20 minutes is a great option to get rid of chlorine. But as in the case of aeration, boiling will leave the chloramine in your water for much longer.
2 ppm of Chlorine will take up to 4 and a half days or around 110 hours to evaporate from 10 gallons of standing water. Ultraviolet light, water circulation, and aeration will speed up the evaporation process dramatically. Chlorine will last between 6 and 8 minutes in 10 gallons of boiling tap water.
Use Hydrogen Peroxide
Hydrogen peroxide is a powerful oxidizer and reacts with chlorine to produce water and oxygen. It is working if you notice small, effervescent bubbles in the pool. For the best results, use hydrogen peroxide that is formulated for pools.
If you decide to place the water in a jug that's left open in the refrigerator, the chlorine should evaporate completely within 24 hours. For quicker evaporation times, leave the water at room temperature.
Flooding Your Grass Is Not A Good Idea
The problem with draining your pool in the yard, if permitted by your local water regulatory laws, is that it will quickly reach its saturation level and increase the risk of flooding your lawn, drowning the roots of your grass, and attracting mosquitoes.
Chlorinated water, such as that from a pool is not suitable for watering plants. High levels of chlorine are toxic to plants. However, water compositions with low chlorine contents may be used, and even prove helpful for the plants.
Two drops per gallon.
Boil chlorinated water for 20 minutes.
Boiling creates heat and aeration (via bubbles), the combination of which is sufficient to remove volatile chlorine after 20 minutes.
VITAMIN C DECHLORINATION
Vitamin C is a newer chemical method for neutralizing chlorine. Two forms of vitamin C, ascorbic acid and sodium ascorbate, will neutralize chlorine. Neither is considered a hazardous chemical.
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.
Keep your pump and filter running. Give the shock a good 12 to 24 hours to work it's magic. If the algae hasn't cleared up after 24-48 hours, clean and brush the pool and add another shock treatment.
Chlorine is a sanitizer, and (unless you use Baquacil products) is necessary for maintaining a clear and healthy pool. Shock is chlorine, in a high dose, meant to shock your pool and raise the chlorine level quickly.
Pool stabilizer is quite slow to dissolve no matter what method you use. It will take 2-5 days to dissolve fully. There are two methods you can use to dissolve stabilizer into your pool water.
When the chlorine has completely finished working, the algae in the pool will turn a white/gray color and will either settle to the bottom of the pool or be suspended in the water. There shouldn't be any more green color and the water visibility should be improving. Run the filter 24/7 and backwash as needed.
It Should Not Be Done Together
This is because when you mix chlorine and algaecide together, it renders both of them useless. Hence, you should first shock the pool and wait for the chlorine levels to fall below 5 PPM. Only then should you introduce algaecide to get the best results.
