What about this one?
I had posted this one earlier but decided to do a T5 fixture instead because my dad doesn't want to pay the huge bill each month for the electricity costs of the T5(but I'm sure I can talk him into letting me get a T5 fixture)
Do the pros of a LED fixture outweigh the cons?
Does anyone have any tanks that they can take pictures of that have a LED fixture on it?

The tank water looks more clear with the metal halide! I like that...is 90w growing all your corals just as well as the 250w metal halide?

Well the halide is brighter, which it should be 346w vs 90w, and the leds are a little more blue. As far as growth I'm not sure. Ive only had a saltwater aquarium since January , I've had the halide for around 3-4 months and I've been running the leds for about 6 weeks, so growth is hard to say.
I don't know if it looks any clearer in person, just the way it appears in a pic.
Maybe this can give you a little idea, I happen to have both halide and LEDs so easy to compare pic wise. My corals ( I have a little bit of every type of coral sps, lps, polyps, shrooms, anemones, ect) all seem to respond well to both lights.

Okay, I'm probably gonna try and find a LED fixture on Craigslist for under 200...my dad will be happier with the electricity costs and I will be happier about the less heat and changing bulbs every 9 months.
Is 174 watts on a LED fixture good enough for a standard 75 gallon tank?what is minimum wattage?

The only issue is that the bulbs are for plants not for corals, may do really well for growing algae in your tank. 6700k is natural sunlight color, which is good for everything really it just tends to grow algae better than the bluer bulbs . Replacing 8 bulbs will be kinda costly unless you get the cheapest bulbs you can find, which will kinda defeat your whole purpose.

Ok, what temperature of bulbs am I looking for? The replacement ones might be a different temperature..but is this a good fixture? I mean can it grow any corals if I get good bulbs?

You want bulbs that are 10000k plus, as far as that fixture goes, couldn't say, don't know anything about it.
