I tend to be in the once a month, or every other month, or 3 times a year camp. A one day long blackout, or even two full days and nights won't hurt the aquarium one bit. Is it natural? I doubt it but who cares if it works and doesn't hurt the plants or fish. A enclosed aquarium is far from a truly natural setting anyhow. IME, plants really can clear up with a nice blackout every once in a while, just not on a regular basis.
