Actually, an alk test would be better. The introduction of an acid to the tank will lower alk before affecting pH. If the pH drops, you already added too much. That said, I have added large quantities of vinegar (and hydrochloric acid) to my tank without any trouble. As was pointed out, if you're killing a few, the vinegar shouldn't be a problem.
