The pH of a swimming pool is raised by adding a pH increaser, which contains soda ash (sodium carbonate) as the active ingredient, and by testing and monitoring the alkalinity of the pool. The ideal pH level in a pool is between 7.0 to 7.6, which basically is near the same pH level as the fluid the lubricates the eyes. Low pool pH may cause several problems such as corrosion of the metal parts, erosion of the tile grout or plaster, skin and scalp irritation and a burning sensation in the eyes and nose.Continue Reading
The following shows how to raise the pH levels in a swimming pool.
Check the reagents that are being used for pool maintenance to make sure that they have not yet expired and are still suitable to use. The reagents should be effective for up to a year, but require complete replacement the following year.
If the testing kit shows that the pH is below the recommended level, pour in soda ash following the manufacturer's instructions. Keep the ratio of soda ash to water within 2 pounds of soda ash per 10,000 liters.
In case the pool's pH level still drops, test the alkalinity levels of the pool after the addition of the soda ash and circulating the water. If it is below 80 ppm, add baking soda at about 1.4 pounds per 10,000 liters of water ratio. Do not add too much soda. Aerating the pool will also help raise its pH levels.
To lower the alkalinity of a pool, test the pool's total alkalinity level, switch off the pool pump, dilute a total alkalinity-lowering chemical in a bucket of water, and pour the diluted chemical into the pool. You need a bucket, a plastic measuring cup, muriatic acid or sodium bisulfate, and test kits to complete the treatment. Ensure that you know the volume of water in the pool, and read the chemical product's label before starting the treatment.Full Answer >
Lowering the pH level of a swimming pool requires adding an acid to the water, usually muriatic acid or sodium bisulfate. Start by taking a reading of the pool's pH level using a test strip and drop kit. The ideal range is between 7.0 and 7.6. If the reading is above this range, add a solution of water and acid.Full Answer >
Baking soda, also known as sodium bicarbonate, can be used to raise the alkalinity of a swimming pool. An article on DoItYourself.com recommends that owners keep their swimming pools at a pH between 7.4 and 7.8, while True Blue Swimming Pools suggests a pH between 7.2 and 7.6.Full Answer >
Increase the alkalinity of a swimming pool by adding 1.4 pounds of sodium bicarbonate for every 10,000 gallons of water contained in the pool. This addition raises the total alkalinity of the pool by about 10 parts per million.Full Answer >
