Just opened the pool about 2 weeks ago and was busy getting the broken discharge pipe fixed. I had continued to add liquid chlorine (12% from pool store) so it is fine at 5 now. But yikes, alkalinity was at 40 and Calcium hardness at 125! Lots of rain! pH is at 7.5. I added 12 pounds of baking soda and thought I had som “cal plus” to add but the container was full of bird seed and so I have none and pool store closed (Sunday). I added two packets of cal-hypo. But I think I need to add more calcium. I have two more packets of cal-hypo. I can’t find a refeeence to adding borax but thought this was ok to add calcium? Can someone let me know if I’m a pinch there is something else to use or is tomorrow ok to add more calcium?
