As far as a conversion rate from pucks to bleach there isn't any. Most people test the water in the evening and add bleach to bring their levels back up to normal. With such a high CYA level you may not need to add bleach everyday, but you won't know without consistant testing for a while.

One gallon of 6% bleach (ultra bleach unscented) will add 6ppm for every 10,000 gallons of water. There is a bleach calculator on a couple of people's signature lines - just search the forum and you should be able to find a thread with a link to it.
