Are you using buckets or a direct in/out-flow water change system? If it's the former, treat per bucket volume each time, if it's the latter you would treat for the total tank volume. Given the situation and the concern about added stress by over-dosing (even though it's advised as safe by the product info) I would be tempted to go with buckets so that you can direct treat the water and not have to add any more chemical than absolutely necessary.
