On most of my tanks, I've calculated (using inside tank dimensions) the volume removed at various levels from the top. I've made marks on the side of the tank that show when 10, 20, 25 gallons, etc., have been removed. Makes it pretty easy...
Adding water directly to the tanks is no problem. Some people add their dechlorinator as the water is added, some put the dechlor in first. It doesn't seem to make a whole lot of difference.
Given how much easier water changes are, and how much more I'm likely to do them with a Python, it's nothing but a benefit to my fish to own one.
