As stated, frequency of water changes are determined by your system and your own willingness to do them. I think most people start with performing water changes weekly or biweekly and as their system matures they can continue lengthening the time given they don't see any loss of coral health. Designing my own system, I put a heavy emphasis on trying to reduce the necessary frequency of water changes. The system is now five months old and I have trouble stretching my water changes past two weeks so I can't say it worked quite as intended. I'm curious if anyone can share their thoughts on this or give some insight as to how maintenance changes as a tank matures past a year and upwards of three or more.
