Yes, that's the method I used with the same water. I think I'm making progress though. I raised the FC to 18ppm last night and it held steady. This evening FC was 17ppm and CC was down to 1.5. So maybe I need to give it more time.

The foamy algaecides were probably your culprit....I can't explain the chemistry, but I do know that they break down into chemicals that can create quite a chlorine demand. Keep it at shock level and stay the course--once you break the stuff all the way down it will be much easier to maintain.
