I just purchased a python "no spill" system and as you know, the advantage of it is that you can add water directly from your tap. They claim that the movement of the water through the apparatus and into the tank is enough to get rid of most of the chlorine. Have others had experience/success using this product adding water straight from the tap? They also state that you can just add some water conditioner to your tank and that will make absolute sure all the chlorine is gone. Is this better? Comments/suggestions?
