Keep in mind that, if you wait until there are significant problems, you will
have to take really drastic action. With nitrates at 100mg/L, a 25% change will
only bring them down to 75mg/L. An additional 25% change will only get them to
56ml/L.

If your fish begin to show signs of distress due to nitrates, you will have to
rapidly reduce the level to below 40mg/L, which will be a *very* large water change.
