Just to set the record straight here, you can keep ANY type of coral
using normal (NO)fluorescent lighting provided you have enough of them
and you place the corals in the correct part of the water column. I
have a 90 gal reef that is lighted with 6-40 watt bulbs (1- 50/50,
2-20k, 3-actinic). The key is the IceCap ballast. The NO bulb produce
approximately the same intensity as VHO with these ballasts. However
the electrical consumption is about 50% greater per bulb (i.e., 60 watts
consumed for each NO bulb).

I have a variety of corals including various SPC (small polyped corals)
such as Porites and numerous Acroporas. However, those high light
requiring species need to be located in the upper third of the water
column to get sufficient light. They may not grow quite as fast as
under metal halides but they do just fine. In fact, some of my Porites
actually are much lighter in color on surface of the coral piece versus
the sides, which suggests they are actually getting more light than they
can handle.

So much for the theory that NO bulbs will not work in a diverse coral
reef aquarium.

If you want to respond to me directly, remove the nospam from the address.
