Thanks. It was late, an any time I tried to work out the ratios, they didn't make sense.
So that would be two drops per week after water change?
OK, just did the ratios, and given the 20 drops / ml for water-like substances,
(5 ml / 60 gallons) * (20 drops / 1 ml) = 1.666666, or 1.5 drop per gallon.
So for my 5 gallon tank, I'd use 7 drops per week. They say to start off small and ramp up, though.
