Depends on your habits. Feeding, etc. You will need to keep a test kit handy to keep up and check yourself. Then you will know how often. But the first problem is getting through the ammonia spike you're soon going to encounter. Did you just get all the fish? Can some go back? If so, I'd do that until the filters have time to establish themselves some.
