is api aquarium salt what you are referring to ? or regular salt , sea salt , i know not to use table salt , i never knew there were so many types of salt , i know i am ignorant , but still trying , btw my smaller pond is crystal clear and doing great , i got the bigger pond to give the fish room , so as of now i am gaining experience and almost feel big headed about it , but this darn Koi has me mistified , none of the other fish have developed any spots in the same pond with the Koi i know its contagious but i am hoping i can stop the spread
