When is your kit supposed to arrive?
Jan is right in that dichlor (which I'm pretty sure is what you've been using --- check the bag) will increase your CYA pretty fast. But, even still, adding 140ppm of CYA in 6 weeks seems like a lot. If your kit is due to arrive within a day or two, I think I might hold off taking the chlorine that high until you can test your CYA yourself. If you find that it is actually that high, then you will need to follow the 'shocking' advice that she wrote above.
