As far as water changes go and dropping the hardness slightly, how do you know
the gills are affected? I have seen no ill affect in my fish doing water changes
with softer water. If your water is 200 ppm and you remove 1/5 of it and
replace it with water that is 100 ppm the end result is somewhere around 180
ppm, a drop of 20 ppm well I call it raining in the pond. :-)
