	This is nonsense.  To remove the elemental chlorine put in
water, you need a reducing agent.  Turbulence will do nothing.

	I'm not surprised.  Small tanks have lots of reducing agents
in them - fish, plants, fish poop, algae.  The question is:- Does
the chlorine damage the fish significantly before it is gone?
I would think that planted tanks would be much better, as the plants 
should take most of the damage from what is, after all, very
corrosive stuff!
