tank filling/waterchanges

Subject: tank filling/waterchanges

I have ordered a bigger aquarium(198 litres for three fancy goldfish))
This will take some filling with a bucket. I was considering a hosepipe but how doe one go on with the chlorine/chloramines?

In topping up after 50% change Is it OK to calculate the amount going in 50% and pre-dose the remaining tanke water with water safe or similar product first?
With my exsisting tanks I usually just dose the new water in the bucket then fill up.
