found this thread because i have been testing this medication under the microscope.. dissolving it in aged water(salinity @ 35ppm) and adding it to a petri dish containing cryptocaryon in its free swimming stage and it does work...
As far as i know only if the ich(cryptocaryon) bacteria is in its free swimming stage.. I dont know exactly how well it works when the bacteria is in any of its other stages.
That is the truth behind medications is that most are only useful when the bacteria is in its free swimming stage but does not kill the rest of the ich that maybe in other stages laying on the bottom of your aquarium. Long term treatment with a medication is the only way to accurately say it does not work...
The reason i believe hyposalinity and high temp. works so well is because the ich bacteria remove themselves from the host (converting to free swimming bacteria) to find higher salinity or lower temperature waters and end up dieing because they can not survive in either of these conditions... It makes all the ich look for better conditions not just the ones that are at the free swimming point of its life..

Actually it does say it right on the side of the bottle which is the reason behind me testing it...
Either way if you meet the requirements to do hyposalinity then do it.. Its the "foolproof" way to riding ich... good luck
