Low light reef options.

Most mushrooms will do ok with plain lighting. Sun Polyps don't care for
light either. Not sure about softies but I have several softies in my system
with PC lighting which was reasonbly priced and works well. Stay away from
LPS corals with plain lighting.

What types of corals, mushrooms etc. can be kept with normal fluorescent
lighting?


Thanks,

Just an observation. Doesn't the depth of the tank, and the the wattage of
the fixture have something to do with what can and can't be grown in a tank?
Take a 50 watt bulb and put it over a 30" tall tank and the tank will be
dark. Put that same 50 watts over a 12" tall tank and you have a bright
tank.

Ann,

Yes the depth matters tremendously. After 2' (60 cms) deep, the light
penetration reduces dramatically. Scientifically, I think it works on
the inverse square principle, in that the light at double the distance
is only a quarter of the light intensity, not half as you may expect,
and so on. If you read expensive aquarium books, where optimum light
is accurately measured at different depths (the Modern Coral Reef
Aquarium etc.), light penetration drops off significantly after about
5 metres.
