Hope this is in the right place! I am currently using Vita-Chem for my betta Neptune and also for a long-finned danio who has managed to damage himself recently too. I am adding it once a week (1 drop per gallon weekly or whatever the instructions are, i forget just now), but it also mentions to add a few drops in between these treatments with food. Does anybody do this, and also does this not seem a little vague?? I'm just interested to see how other people use it. It does seem to be a good product but the dosing instructions don't like me so I stick to once a week to be safe!
