"Good numbers" are very subjective. Are you using drop-based testing or test strips? Can you post a full set of numbers here taken with a drop-based kit so we can give you more direct advice? 5 bottles of bleach so far in a 22,500 pool seems pretty low....but what you need to use is the amount it will take to get to shock level and hold it until you're not losing any chlorine overnight., How much that will be depends on your CYA level to start, and how consistent you are about keeping it at shock level. So...with a good set of numbers to start with, we can help you figure out how high the chlorine needs to go.
How does your water look?
