my wife works for a dentist so I have unlimited supply under the name eugenol. I prefer
222. What i have found over the years is that thru indiscriminate use of antibiotics, many times these days we have to use a cocktail of sorts for injections and the more you need to put the koi down in sucessive days the longer it takes to put down as they seem to build up a resistance to Oil of Cloves. I found that it takes as long to bring them out as it does to put them down, and after several days of use, I start to build anxiety when they don't come back quickly. So for ease of stress on myself and my koi, I go a different route.....
