Bingo.

I dose for tank volume AS I'm adding the water.
You have to dose for the entire volume of the tank because when you fill the tank the chlorine and chloramines from the tap mix into the existing aquarium water and contaminate it so you have to dose for the entire tank.Just wondering: why would you need to dose Prime for the entire volume of the tank? There would be no chloramines in the tank to start. It would only be the amount introduced with the fresh tap water. Dosing for the entire tank would be over-dosing. You can do that safely with Prime, but it is more costly.
