I personally don't like doing large water changes (anything over 30%). I know 
lots of people talk about doing 50% and larger water changes but I would rather 
do many smaller water changes than a couple big ones.  By doing frequent water 
changes it actually keeps the water more stable and consistent. Just because 
your water tests are ok doesn't mean you should not do a water change. There is 
more to your water than just the parameters you test. Doing frequent water 
changes will help to keep other variables in check. In reality the more often 
you do water changes, the less drastic changes there will be.
