The industry rule-of-thumb is that you want a salt chlorinator with at least 1.5x to 2x the capacity of your actual pool size. You want to ensure more-than-adequate chlorine production for your 22k-gallon pool, so that it doesn't have to run all the time at a high output setting, and only have it just keeping up in normal circumstances. The larger the cell, the less hard it has to run to do the job, and the more power you have in reserve to deal with pool problems should they arise.
