I would probably hold off on the water change for now and allow the bacteria to build a bit more. We usually recommend two weeks at the earliest, one month preferably, and then after the first month, you can set whatever routine you plan on having. For example, I do a water change weekly in my tank. It should depend on your schedule, size tank, number of inhabitants, and types of inhabitants. I suspect the cycled filter media created some of the nitrates, so you could change that out for now and see if that helps, wait at least 4 more days, and then do a 10% change. Nitrates are not too concerning unless they continue to climb. Live plants will help remove them as well, think about adding some plants to the tank if you have decent lighting. They really are not hard to keep if you have good lighting. Lots of easy plants out there, be sure to buy true aquatics.
