14 days is pretty doable, providing you provide the ideal conditions for the bacteria to reproduce.
As for the chlorine killing filter bacteria/fish etc, the effects that chlorinated water have on a filter colony are negligible, the concentrations of chlorine in tap water are designed to kill the smallest of colonies, the size of the colony in your filter will be many orders of magnitude larger, so chlorinated water will affect it, but not to the extent that it is commonly talked about...you're taking a few percent if that.
The effects of chlorine on fish however is a different matter, the concentrations at which chlorine is said to kill aquatic organisms is between 0.16-0.21 Mg/L, this was tested on Fat Head Minnows, so variation across species will occur, the average chlorine concentration in my water supply is 0.37Mg/L, so if I do a 25% water change 0.0925Mg/L of chlorine will be added to my tank, so therefore there are concentrations that shouldn't kill fish, or have a considerable affect on my filter bacteria.
