You would think this question is easy to answer, but everyone has a different approach. I personally do very small water changes on my reef, say 2% per week, unless I see issues in my alkalinity and calcium testing that give me a reason to consider larger scale water changes.
Many people will argue for larger water changes, and other do almost no water changes at all. You will find a wide variety of methods that people find successful. The key is to find what works for you and judge from the visible response of your animals what you feel is best.
