If the Chlorine is in the 5-10 or 20 range is it safe to swim? Water is clear as day it looks great. I tested tonight before I put anything in and FC was 3.2 so it is holding the chlorine better already but CC is still 1.0 Ph was around 7.3 it was between the 7.2 and 7.4. I put 4lbs of borax and 1 gallon of chlorine because I wanted to wait to see about the swimmability before I went and dumped all that chlorine in. Thanks everyone
