I was talking to my LFS fish guy about water changes and he made the statement that if it ain't broke don't fix it. What he meant was that there is no reason to do a water change if you test levels are normal. As long as the test results are clean there is no reason do a change even if it has been a few weeks since the last one. Is this true, should the need for a water change be dictated solely by the results of the tests?
He stated that he only has to change out water about once a month.
