So I just drained over 2/3 of our pool and going to SLAM it. I have ran the tests for my PH and the levels are at 7.5... I am curious how much chlorine/bleach I should use? After running the test it looks like I have .5ppm, and I am confused at what level I should SLAM it to as the recommended levels are 3-7 (pool-school/recommended_levels) maintenance, but I am seeing shock levels on here at 30ppm.
I have 10% liquid chlorine, and I am am just curious if I should raise them to 30ppm or the 3-7ppm with pretty much clear fresh water with no signs of algae?
If 30, I am showing via the http://www.poolcalculator.com/ to add 334 oz or 2.2 Gallons or if 7ppm I should add 74 oz or 2 quarts 1 cup 2 oz.
