Reef lighting--

[waterbaby76]

Ok -- now Im REALLY confused. How did people manage to have a reef aquarium b4 VHO lighting became available? null

I think metal halides were available back then, but I could be wrong. Maybe they just used a whole load of NO bulbs? Or maybe they didnt keep reef tanks bakc then?

People used NO lights or natural sunlight. They also were met with less sucess!! Many corals considered easy or at least possible now were not then.
