Ok, received an email reply from FishVet and although they would not supply the formulation, they did state the base chemical is 5-nitroimidazoles (Also in Kick-Ich). If you are not familiar with this group, it is comprised of antibiotics that are prescription drugs to treat intestinal infections such as bacterial and flagellates in humans, animals, and livestock along with other pathogens. I can only assume that some of the other meds used in conjunction are to rectify the rapid degredation in water-borne administering. Here's some background information: DNA-Synthesis-Affecting Drugs I: Alkylation Reactions -- Encylopedic Reference of Parasitology
Exerpt from Reefkeeping:
"Treatment Option 8: 5-Nitroimidazoles
There is another class of products on the market that are alleged to be a reef-safe, alternative, anti-parasitic medication for Cryptocaryon irritans
. The active ingredient of this category of treatments is 5-Nitroimidazoles. I have only used this type of product a few times, but never in a reef tank, so I cannot speak to those claims. I found these to be moderately successful against Cryptocaryon
, although it required twice as many applications as the manufacturer stated on the instructions to affect a complete cure. My biggest complaint is how expensive it was, in particular accounting for the amount and time needed to affect a full cure. Anyone who wishes to try one of these products should perform a search on several of the online message boards to get additional feedback prior to purchasing. Based on my own experience alone, I cannot recommend them."
If I get more info I will update this post and as I stand, still, I would not ever use a medication of sorts in a main display unless dire needs.
