just dechlorinate the water before it goes in and the bacteria will grow, not much you can do after a water change other than monitor the health of the fish.

Certainly! Many aquarists dechlor for the whole volume of the tank at the same time that they are directly adding chlorinated tap water to the tank.can you use a dechlorinator whilst the fish are in the aquarium?

It is wise of course to consider the dosing recommended by the manufacturer of the dechlorination product. They can vary greatly in concentration, meaning that the appropriate amount to dose per USgallon or liter can vary quite a bit.
Another consideration is that beginners who are cycling (either fishless or fish-in) should limit any "overdosing" of the dechlorination product to not more than about 2x (meaning 2 times what the manufacturer recommends) because once you pass beyond 2x dosing, the chemical can have a negative effect on the growth rate of the N-Bacs (the second of the two beneficial species the beginner is trying to grow in the filter.)
Once the filter is mature of course, this concern is no longer relevant and overdosing somewhat beyond 2x is unlikely to be harmful although it could be wasteful. "Conditioning" (the adding of a dechlorination product) is a form of insurance. In a strictly technical sense it may not always be needed since water and species conditions vary widely, but conditioning is very cheap and handles the situation where water authorities overdose the chlorine to clean their pipe systems - this happens more often than we aquarists would like.
Hope this helps,

Just wondered after how long is the filter likely to have the right ammount of bacteria in the media?
