Some folks have the additional burden of dealing with tap water with high nitrate levels. It can be really frustrating to attempt removing nitrates with PWCs when the new water being added into the tank already has high levels.
I know a guy from another forum whose tap water goes about 80 PPM
when tested for nitrates! 8O
