Has anyone ever done a test using regular tap water to wash off some biomedia and tested to see that 100% of your bacteria were killed off? Probably not.
Is chlorine bad, yes? Will it kill your entire filter rinsing it off in tap water? That part is probably more debatable.
When I kept turtles, I know a turtle keeper who had a big stock metal tube and 3 Rena filters just filled with sponges and pads. A few times a year he would break it down and hose it all down, having a snapping turtle in it, they get messy and never had a problem with cycles, spikes, etc. He posted an interesting article about actually showing the resistance of the bacteria that grows in our tanks and filters, I will try and find it again.
I know we are under the need "dechlor in our tap water" or it will kill your entire filter sort of idea, but I'm not sure how much it has been proven or just something that's better to dechlorinate for the sake of the fish but really doesn't affect our biofiltration to a huge extent, I'm not sure.
