One point is that hard-water stains can collect on the glass and reduce your
light. In our acidic tanks that should not be too much of a problem. I also
don't have any hard water problems at home where I have a water softener but
I get a lot of it at work where there is no softener. I've taken to mixing
the tap water with distilled.
