My CH tested at 175 and TA at 50 this morning. I picked up a bucket of calcium chloride and a bag of Arm & Hammer Baking Soda this afternoon. According to Pool Math, 25 lbs of calcium chloride will bump my CH from 175 to 260 and 9 lbs, 6 oz will bump TA from 50 to 70. I am new at this and this is my first time adding any chemicals other than liquid chlorine. My pool water is crystal clear and I don't want to mess anything up on Labor Day weekend so thought I would double check with you all. Is there any particular order and/or time between that I add the calcium chloride and Baking Soda? I decided to try and move numbers to the bottom end of the suggested range and then test again so that I don't overdo it. I appreciate your feedback.
