I tested with the 2:1 method and it was a pretty yellow orange like the 5 is on the test kit, so multiplying x 3 would make it 15. I had just added a 3 quart bottle of chlorine after I wrote the last reply. I will test again in the morning to make sure it is still there. Do I need to keep up with the stabilizer or pH right now or just worry about the shock until it is clear, which should possibly take how long? I would like to be able to enjoy the pool this weekend. It is 100 degrees here in lovely SC.
