Different people tell you different things, but it mainly relates to the amount of use the pool gets, the weather, your own personal ability and whether the pool or spa is problematic or not.
During winter, once a month is generally fine unless you're having problems, summertime if you're having heavy loads then you might want to get it done once a week. Problems during summer might need you to have them done twice a week or more if you don't feel comfortable with testing yourself.
