My concern would be that the dose would be too small to make enough difference.
According to that article:
"In the prophylactic treatment one we stay at the same dose every day. It should be noted, and will be repeated, that the dose required to achieve a certain concentration needs to be added at least once a day."
Maybe for prophylactic pourposes dripping might be OK:
"When treating an aquarium on a preventative basis only, it is not necessary to add real large dosages of Vitamin C. All we are trying to achieve is to provide the fish and other animals with a constant, low, supply of Vitamin C to build up their immune systems over a period of time, and take advantage of the other benefits offered by this vitamin."
For folks complaining about their skimmers going crazy:
"Use a real pure type that does not contain binders, starches, sugars, emollients etc. Read the label carefully before making a selection. Eliminate any possible problems by using such a brand or type of Vitamin C. Not only can they be detrimental to the water quality, but they can affect the way your protein skimmer foams (too heavily in most cases)."
I CAN'T STRESS ENOUGH, THAT EVERYONE HERE WHO IS DOSING WITH VITAMIN C, READ THIS ENTIRE ARTICLE:
