No, that is not it specifically, but I don't know for sure. I first discovered the product in Japan. Mr. Sakai uses it when he transports his Koi by truck from Niigata to Isawa. He also uses it with OTC to get rid of bacterial gill infections. I asked Miwa about sending it over to the US and she said it is made in Oklahoma. The company is Bio-Cide International and it is Chlorine Dioxide 5%.(The active ingredient is the same) They make it for food processing plants, bottling plants and industrial use. It comes with citric acid activator crystals. You mix the two together and then apply at whatever dose you need. For Koi transport it is 50 - 100mls per ton of water. For treating gill disease it is 200 - 300 mils per ton and for total sterilization it is 1000 mils per ton or higher.
P.S. Algaefix is registered with the FDA as a pesticide.
