A low pH (potential hydrogen) level in a swimming pool can be caused by rainwater and foreign particles entering it and changing the chemical composition of the water. Corrosion of metal accessories, stinging eyes and nose, rapid loss of chlorine, and dry and itchy skin and scalp can all be signs of low pH levels in the pool. The low pH level also reduces the cleanliness of the pool. Regular checks and chemical treatments can help maintain the pH level. Use the following tips to increase the pH in your swimming pool.
Step
Step 1. Test the pH of the pond water at least twice a week
Use test strips made specifically for pool testing. Record the results for future reference.
Step 2. Determine the size of the swimming pool and the total volume of water in it
Measure the average depth, length, width, and diameter of the pond. All linear distances must be measured (or converted to) in meters for uniformity of work processes.
- Calculate the volume of water in the rectangular pool. Multiply the length, width, and average depth of the pool together. For example, the equation for a pool that has a depth of 3 m, a length of 2 m, and a width of 1.5 m is 3 x 2 x 1.5; then the pond contains 9 m3 or 9000 liters of water (1 m3 = 1000 l).
- Use the diameter and depth measures to determine the amount of water in kiloliters (m3) in a circular pond. Multiply the diameter by the diameter (back), then times the average depth. Multiply this result by 0, 8. For example, a pool 3.5 m in diameter and 1.5 m in average depth would have the following equation: 3.5 x 3.5 x 1.5 x 0.8. Total The volume of water contained in the pond is 15 kl (15,000 l).
- Determine the volume of water in an oval-shaped pool. Multiply the long diameter, the short diameter, the mean depth, and the number 0.8 together. For example, a pond has a long diameter of 3.5 m, a short diameter of 2 m, and an average depth of 1.5 m; then the equation is: 3, 5 x 2 x 1,5 x 0, 8. The pool contains 8 kl (8,000 l) of water.
Step 3. Add soda ash (sodium carbonate) to increase the pH of the pool water
Soda ash may be labeled with many different manufacturers' names. Make sure the basic ingredient contained in this product is sodium carbonate. Do not use soda ash in pools lined with fiberglass or vinyl.
- Circulate the water while adding the soda ash to it. Keep the pump running while the chemical is added to the water.
- Increase the pH of the water between 7.2 to 7.4: Use 85 g of soda ash for 19,000 l of water; 170 g for 37,900 l of water; 255 g of soda ash for 56,800 l of water; and 340 g for 75,700 l of water.
- Use soda ash to increase the pH range from 7.0 to 7.2. Pour 115 g of soda for 18,900 l of water; 225 g for 37,900 l; 340 g for 56,800 l; and 455g for 75,700 l of water.
- Measure and pour soda ash into the pool to increase the pH level to a range of 6.6 to 7.0. Use 170 g of soda ash for 18.900 l of water; 340 g for 37,900 l; 455 g for 56,800 l; and 630 g for 75,700 l of water.
- Pour in the soda ash slowly so you don't get splashed.
Step 4. Re-measure the pH level of the pool water after about an hour
