Some pH test kits require you to fill a small tube with pool water and add drops which change color based on the pH.
For example, the color of your test strip might show the yellow of a banana. According to your product, this means the pH level is 7. 2. You’d want to raise the pH by a minimum of . 2 and a maximum of . 6.
For a rectangular pool, the formula is length X width X average depth X 7. 5. If your pool has a deep end and a shallow end, measure the depth of each, add them, and divide by two to figure out the average depth. For a round pool, the formula is diameter X diameter X average depth X 5. 9. If part of the pool is deeper, take the shallow depth plus the deeper depth and divide the number by two. For abnormally shaped pools, adjust these formulas to figure the gallons (liters) in each section, or ask a pool expert for an estimate on how many gallons (liters) your pool holds.
For example, you test the pH of the water and it shows 7. 2. You want to raise it to 7. 6. Your pool holds exactly 10,000 gallons (37854 liters) of water. Use 12 ounces (340 g) of soda ash for the first round.
If you don’t have a pool store near you, check at a water treatment store, hardware store, or big-box store like Walmart.
It’s important to fill the bucket first and add the soda ash second.
Remember, don’t put the soda ash into the bucket before the water.
If you want, use an old plastic cup to scoop water out of the bucket and toss a cupful at a time into the pool.
If the pH isn’t where you want it to be, check it in a day or two and add more soda ash in the quantities you already figured.
