I dont believe so..The problem is that when your water level goes down,if you add water,then it actually gets harder as water is evaporated but minerals arent.
And when you do a water change,well,in go the minerals,BUT it is not getting any harder due to the fact that you are taking out some minerals as well.
I believe the KH can be taken care of but not the GH..And I may have that backwards.. ZEN
