to much light????

[norcal]

hi i have a 135 gal that i am thinking about setting up as a reef tank. i have an opportunity to buy a light fixture and hood (good looking hood). the fixture includes 3 175w MH's and 2 6 foot actinates. this seems like a lot of light, wondering if it might be overkill. (but not sure, i dont have a lot of experience). also i was hopins someone could give me an idea of how long each of these light might last. thanks for the help :yes:

That's not too much light at all. In fact, you would probably need at least 3x250W MH if you were planning an all-SPS or clam tank.
Depending on the color of the MH bulbs, they would need to be replaced anywhere from 8-12 months (high-K bulbs need to be replaced sooner than 6,500K or 10,000K bulbs), and the actinics need replacing every 6-12 months (again, depeding on the type of fluorescent bulb and the ballast).
