The CYA test on 'guess strips' is the worst of the lot -- you should ignore that reading. Essentially, you have no CYA. You'll need to keep dosing EVERY night, till you get some in the pool. If you got a Taylor K2006, do not test for a week -- there are only 3 - 4 CYA tests in that kit -- since it takes that long to dissolve what you put in. If you put it in via the filter, and then clean the filter before a week of circulation . . . you lose the CYA. If you are running your pump on a timer, it can take even longer than a week.
