You need to dechlorinate the pool water if you are going to discharge it.Natural sunlight in your backyard can be used to dechlorinate your pool, but it will take a couple of weeks.A variety of chemical solutions can be used to speed up the job.Environmentally responsible products such as vitamins C-based dechlorinators have a negative impact on fish and wildlife.
Step 1: Add chlorine to your pool.
You should stop putting chlorine tablets in your swimming pool.The water will be dechlorinated gradually.You have to leave the pool uncovered for two weeks.
Step 2: A bucket can be used to dechlorinate a small amount of water.
You can use a bucket if you only need to dechlorinate a small amount of pool water.Put a bucket of water in a sunny spot.It's best to leave it in the sun for a week.
Step 3: Run the pool pump.
Continue to run the pump even though you have stopped adding chlorine.The pump will help ensure thorough dechlorination by circulating the water in your pool.
Step 4: A dechlorination product can be purchased.
Dechlorination tablets or liquid can be used to dechlorinate your swimming pool.Sulfur dioxide is the most common chemical used for dechlorination.You should make sure that the product you buy from the swimming pool retailer complies with the EPA standards.
Step 5: Dechlorination tablets are based on vitamins C and C.
If you want to dechlorinate water, you can use ascorbic acid or sodium ascorbate.Oxygen is not removed from the water with the help of vitamins C and D.The EPA's Clean Water Act supports the use of vitamins C and D in dechlorinating water.They are easy to handle.Sulphur-based products are more expensive than vitamins C and C.
Step 6: Discuss carbon absorption filters with a pool professional.
If you want the most thorough method of dechlorination, carbon absorption is the way to go.It is more expensive than other methods.If you want to know about the carbon filters that are available for your pool, you have to ask a swimming pool specialist.You can ask the pool professional if there is a carbon-based filter that would work well.
Step 7: Put it in the pool.
It is possible to dechlorinate your pool with an appropriate amount of sodium thiosulphate.Warm water can be put in a bucket.Add the required amount to the bucket.The bucket should be put into the pool.If your pool contains 5000 gallons of water and the total chlorine is 50 parts per million, you will need to add 1.56 pounds of sodium thiosulfate.You can use an online dechlorination calculator.
Step 8: The levels of chlorine need to be tested after two weeks.
After two weeks without adding chlorine to your pool, you should test the chlorine levels.The most accurate way of measuring chlorine concentrations is through a DPD test, although test strips or a colorimeter can also be used.The test kits have a comparator.You can compare your sample to the standards.You put your sample in the slot and compare it to the standards on the side of the instrument.A colorimeter uses white light to determine chlorine levels.It isn't included in standard DPD test kits.Test strips can be used to determine chlorine levels.They are the cheapest option.
Step 9: You can get a water sample for testing.
You will need a DPD test kit to get water samples.You can get a water sample from the elbow depth of the pool.The recommended drops of reactant should be added to the tubes.Turn the tube upside down with the cap on to mix the solution.
Step 10: The comparator should be held at eye level.
If you want to perform the test in good lighting conditions, you will need to use the color comparator included in your test kit.If you are outside, you need to hold the comparator at eye level with the sun to the side, as opposed to shining directly through it.You need to remove your sunglasses to read.You will need lighting that is close to daylight if you are inside.
Step 11: The test kit has a comparator that you can use to compare the color in the tube.
You can use the color chart on the front of the test kit to determine the chlorine level.You can find the closest match and note the chlorine level in a notebook.
Step 12: A colorimeter can be used to determine chlorine levels.
An instrument called a colorimeter could be used instead of the comparator.A white light beam is sent through an optical filter.The water sample is in the top slot.The sample will get a white light beam when the colorimeter is turned on.The amount of chlorine in the sample will be shown on a digital display on the front of the instrument.
Step 13: Test strips can be used.
If you're looking for a cheap way to test chlorine levels, you might want to use test strips.You can dip the test strip in the pool.Wait for the number of seconds on the test strip kit to be indicated.The test strip needs to be held horizontally.The test strip kit has a color chart.You should note the chlorine concentration when you find a match.Test strips will give you a good enough reading even though they are not as accurate as a DPD test.
Step 14: Do you know if the chlorine levels are close to zero?
If the chlorine levels are close to zero or at least at an acceptable level, you should use one of the testing methods.If the water sample shows an acceptable level of chlorine, you have successfully dechlorinated your pool.If the chlorine level is not acceptable, you can either dechlorinate naturally or use a chemical method.
