hi ,I am new to this forum and it fact this is my first post,i feed spectrum food this has garlic added ,it is quite expensive but goes a long way . if you feed this food it is extremmly unlikely you will get whitespot
I keep discus and make my own food, some say garlic to a fish is like blood to a shark but tbh i have made it with and without and not seen any difference, you really would be better adding boiled spinach as it has more vitamins and iron
