Thanks for getting back to me. The numbers today are:
pH 7.4
cl 5 ppm
alk 70 ppm
CYA 30 ppm

I have been using the kem-tek dichlor for a few days now. Not sure if it's the dichlor, but the cl levels seem much more stable over the past few days. (It has also been cloudy and raining for several days.) Thanks for your help!

I should also add that the water looks great- nice and clear. The only problem is the crud that is accumulating on the bottom of the pool.
