hello, i want to set up my sw tank as a reef. i was wondering if i can use a shop light fixtures and put a VHO bulb in it. also what size bulbs does the avrage shop light tank? like t-8 or t12?
 
okay i looked it up and after about an hour of looking i have found that standard shop lights are t12 bulbs, so why cant i get a 24 inch shop light and put two 75 watt bulbs in it? any reason why i have to get a 300 dollar system to get corals?
 
Small Polyp Stoneys (SPS) are of the most light dependent corals. They need incredibly high lighting, no less then 4 watts per gallon. 5-6 watts per gallon will suffice.

Most corals need very high lighting so invest in some Metal Halides. If you havent got SPS lighting around the 3-4 watt per gallon area will do.
 
Metal Halides which is the ideal light (Apart from actinic's) are extremely expensive to run. Using on average 150-250 watts per MH, they arent cheap. So running a reef tank is far more with corals.
 
I have kept a reef tanks now for the past 8 years (wow time flies) and have used standard fluorescent, power compacts and metal halides. All of which I have been able to keep corals. However, the trick is your coral selection with regards to your lighting. Some corals require very little lighting (need to feed these in most cases) and others do require the strong lighting like metal halides (SPS for example as mystix pointed out). I do also have some friends that sucessfully keep reefs with VHO and T5 systems. What it really boils down to is the choice of corals you plan on keeping. However, I really don't recommend standard fluorescents. VHO,T5 and power compacts can be used to keep most soft corals and some hard corals as well. SPS and clams however require the metal halides. Do your homework on the types of corals you would like to keep then chose your type of lighting. Another thing not all corals do well under very strong lighting! Low light corals are found at greater depths on the reef. These coral can be kept in high light systems but need to be in shaded areas in the lower part of your aquarium (bleaching can occur if placed in direct strong lighting). Choosing lighting for a reef tank is not an easy decision do your homework. Furthermore, reef tank owners all have their prefered lighting systems and swear by it. Funny thing not everyone has the same opinion so I guess you need to find the system or combination of systems that works best for you.

Good luck
 
some SPS will do well under PC lighting. montipora capricornis and montipora digitata are two of the better ones under that lighting.
 
Personally I have not kept any SPS under PC lighting so I can't comment on it. But Atarax demonstrates that with good homework on the corals you would like to keep, you can have a nice reef tank without metal halides.
 
can some one tell me what kelvin number is good and what number is bad for soft corals?
