    Nutrafin Aqua Plus dosage help please!

    I am trying to make up a one litre bottle of tap water treated with Nutrafin Aqua plus to store to use for small daily top ups when the water level dips/evaporates in our Fluval Edge 46l tank. Now going by the directions on the bottle if 10ml treats 37.8 litres of tap water so... if my maths...
