The person that wrote that top article posted above does not mention any of the possible drawbacks to using vinegar. It is not necessarily the win-win situation described. While it can be useful, and is a good way to deal with excessively high pH (above 8.5 or so) or with the cases where a little more potency of the limewater would be good, it does drive bacterial growth.

Whether that is good, bad or otherwise depends on your other husbandry practices, but its impact should not be ignored. It can result in reduced O2 (especially if you add it rapidly), certain visible bacterial growths in some cases, and also possibly in the death of macroalgae.
