9ppm FC with CYA < 30 is pretty high - it's OK it'll come down quick. Please see http://pool9.net/cl-cya/, it explains the basis for the pool care method taught here. Also read the other guides on poolsolutions.com and the stickied threads here, especially in the testing and chlorinating forums.

I'd raise CYA a bit more. How did you get stabilizer in there in the first place? Don't test CYA too often as there's only a few tests in the kit.

Calcium is not a problem for vinyl pool unless it gets over 350 or so.
