The normal dose is 50ml per 1000 ltrs, the 20ml dose is for dechlorinating and neutralising potassium permanganate.

As Ged says, you cannot overdose and to be fair if you have a specific issue such as wounds then it may be better to put a bit extra in. You can redose as necessary really, so it varies, but a monthly dose can be very beneficial. A 40% a week water change will dilute the effects substantially.
