what kind of lighting

i have a 75 gallon sea clear system11 i want a canopy light but what is the wattage i would need for reef system:

 

Thats a big topic here at 3Reef. Lets start by asking whats your budget?

 

If you wanna do it right the first time 2 250W MH with a good ballast/reflector combo would do wonders! (If you can't tell I am getting ready to buy some new lights!!) It's not cheap... if you get good deals ON GOOD STUFF the setup is around $500.

 

i dunno what your really looking for here but for a reef you looking for 4-7 watts per gallon of water you want to go more if you can and they cant be any old lights you want probably vhos or metal halides

 

T-5' or MH's. VHO and PC's are old technology and the reflectors aren't as efficient as T-5's and MH's.

If you go T-5 use the 48" TEK fixture with:
2x ATI Blue Plus
2x ATI Aqua blue special
2x ATI Pro Color

This is what this lighting combination looks like on a 75g.


If you go MH use the Lumen Bright mini (16"x16") reflector. I would recommend the Lumenarc mini III but that's too much spread for an 18" wide tank. As for bulbs I would recommend 250 watt MH's on IceCap's.
