I want one of these lights.
Anyone with some knowlege on this subject is appreciated. I want to know whether I should use 70, 150, or 250 watts, what differences in kelvin rating, color, etc, I should know before I buy.
Do corals need a different spectrum than plants?
Clamp on type metal halide for 30 gallon long planted.

Corals DO need a different spectrum than plants. I learned recently that if you put a marine bulb on a freshwater tank, the light will benefit algae growth more than plants.
Hopefully someone else can address the rest of your question.

I'm vasillating on buying one of these clamp-on lights. I've seen them in action at my LFS and they're beautifull. I want that shimmering effect only a point source light can produce.
They go for about $200 for a 150 watt fixture.
I may just save money and buy a new bulb for my 95 watt PC.
The thing is, I would have to remove the PC to use the clamp-on, and the PC has an actinic bulb that really lights up the Cardinal tetras nicely.
I'm still thinking. It would be best probably to buy a combo of flourescents and metal halides (2 MH's). These are a bit out of my price range though.

If anyone knows of a cheap combo of high output flourescents and MH's I would be interested. Maybe One MH with a couple flourescents as this tank is only 18 inches deep.
One a different note on the same thread (don't like hogging up the site):
I just bought 9 Gold Tetras which are really nice for this tank. They school together and their school often intertwines with the Cardinals in beautiful ways.
One of these new acquisitions has a red upper eye lid. It looks just like the other gold tetras but it's the only one with a red upper eye lid.
Anyway. I love this tank!
