pH Level Of My Pool
by Ada
The pH level of my Intex pool (15 feet diameter) is very low and I have put in 2 boxes (in total 2 lbs) of Arm & Hammer Baking Soda into the pool. The PH level is not going up. The pool is about 3,600 gallon of water. How many boxes of baking soda should I use to raise it from 6.8 to 7.6-7.8? Thank you. Ada Thanks for your question Ada As a general rule for the pH level of your pool it takes 40oz. (2 1/2 lbs) to raise a 20,000 gallon pool's pH 0.1ppm. Swimming Pool pH Levels If you don't have a Taylor Reagent K-2005 or 2006 test kit I would encourage you to get one. It takes a little getting used to but it's worth it because it will give you the most accurate reading. Water Testing Kit Your pool is 3600 gallons and you say you're getting a pH reading of 6.8 and want to raise it to the correct level of 7.6 - 7.8. Using the above formula you would probably need 10oz. of sodium bicarb to raise the pH level 0.1ppm. To raise the pH to 7.6 - 7.8 you would use 70 oz. or 4lbs. of bicarb. You can get a bucket filled 1/2 way with pool water and add the bicarb. Stir it with a stick then walk it around the perimeter of the pool (starting in the deep end) with the filter running. After the water has a chance to completely circulate through the filter, about 1 - 1 1/2 hours, check the pH again and make another adjustment if needed. Swimming Pool pH Levels Start off slowly and work your way up when adding chemicals. You can always add more but it's a bit more difficult to take them out. Let me know how this works for you. Thanks for your question and have a great day Robert New Question Title: Arm & Hammer Baking Soda For Raising My pH Level By: Mary-Ellen Date: June 8, 2011 I brought Arm and Hammer baking soda to bring up the pH level in my 20,000 pool. I put 4 lbs. in the water and it did not raise the level. Should I put the rest that is left out of the 12 lb bag? Answer By: Robert Date: June 9, 2011 Thanks for the question Mary-Ellen To raise the pH level of a 20,000 gallon pool 0.1ppm, you would use 2.5 lbs. of baking soda with the pump on. Swimming Pool pH Levels What I would need is a little more information from you such as: *The current pH reading of your pool *The target reading *How you added the baking soda (did you make a slurry out of it, add it in one spot, broadcast it around the perimeter, etc.) *Was the pump on when you did it? Your pH might be very low and the pool would require more baking soda, but it's hard to know. Without knowing the above it would be a little difficult to give you a correct answer. Please answer the above questions and I'm sure I can help. Robert
