Hi momfromMI,
Doing a series of partial drains/refills will get your CYA to a managable level. Once the CYA is down, you can shock successfully.
A good test kit is the BEST investment we made in our pool. I recommend the TF Test kit sold by duraleigh, one of our members. He also has fantastic customer service. There is a link to his site on the home page and a link in my sig. The kit will put you in control of your water.
