It's very important you follow med instructions especially where concentration of the active ingredients, when they will deactivate (like prazi does in 3 days) and the impact they might have on your fish, are concerned but sometimes we have to skip or break most of the instructions for our fish's sake because not all the time, it will work in similar situations. Yes, continue another 7 days but I always advise 10 days which is the best bare minimum to ensure the ich is completely destroyed. If the treatment duration is shortened, then you will likely produce resistant strains of ich and these strains are an absolute PITA to kill off. I think I'm kinda wordy today.

Do the medication companies print "3 days", knowing you'll be back for more meds??
Let me retract my statement. Instead of saying "ich is always present in the aquaria", I will say "Ich is always present in my aquaria!", lol.
In the future I will continue meds for a full seven days after the last visible white spot has been seen, and hopefully that will be the end of that.
