CONGRATS! the answer is that it depends on what your nitrates do over the course of a week given your bioload. if you are fully stocked, then i'd suggest 10% weekly to maintain about 10ppm. if your nitrates go up over 10ppm, increase your pwc volumes.
if you have live plants that take care of your nitrate, that can work. but if you don't, then water changes are essential to keep nitrates down to fish safe levelsIn my opinion, there is no need to change...
FYI, maybe I am lazy, but I haven't change water for my 3 tanks for months. I just leave the eco-system do the job.
