Well, cf's will be fine for what you have listed but YOU will want to keep more.
Save up and buy a decent T5.

How about metal halides?

Those seem to be the best for growing anything, but you have to watch out for heat issues.

so T5 is the best way to go? Any suggestions?

No, I'm not saying T5's are the best way to go. It really depends on your $$ and what you intend on keeping, but T5's and MH are way better than CF's.

I will be upgrading soon and I'm either going to get a TEK or ATI fixture.

If I've learned one thing in this hobby, it's to not skimp on equipment.

I am way low on cash lol. The CF's that I listed are about half the price of the MH's so they are looking much better right now. It all depends on the sale of another tank I have. On that tank I had a TEK system and I was under the impression that it wasn't sufficient. That is why I downsized the tank so I could afford better, but smaller equipment.

A 4 bulb t5 system is how I would go.

Well while the fixture has good specs I am not so sure on the quality since its $90 and a good reef bulb alone will cost at least $50 each.

I don't want to discredit the ebay fixture you are considering but often times in this hobby you get what you pay for. If you have to ship it back to china for warranty work you might as well throw it away and get another.

A budget halide that comes with a good bulb/reflector and doesn't need a canopy to look good might be one of these. This would be hung from the ceiling. I would go with a 20k bulb.

That is the exact same system I have on my 55Gal. 4 bulbsx54w (48" obviously). Nothing grows or even opens in my tank for that matter, so I threw everything in my smaller tank with borrowed CF's

I agree, look into the Wave Point fixtures. Great price and amazing factory bulbs!

With softies like you mentioned above (polyps, mushrooms xenias), you will grow *****ing ones with a PC fixture but understand that the bulbs for replacement will need to be ever 10 months (at least yearly) and two bulbs will run you about $50-70 whereas a T5 will allow you a ton of bulb combinations and you replace those every 12-15 months and they are $12-15 a bulb.

wow! I have nowhere near that much money right now. I'm trying to sell my 55 with the sunlight supply lights above to be able to "deck out" my smaller tank with the best lights (I can afford of course) and a skimmer and everything.

if you can show us a link, it might give us a better idea of what to look for. There are HORRIBLE MH out there, and there are great ones.

I would say that without a doubt you want more than the 2 CF lights.

I would honestly try and save up about $200 and get yourself a cheaper, but still nice, t5 set-up. Like the Nova.

With the CF, the real cheap fixtures tend to burn out bulbs and ballasts within a year. Really would save the dough and get the t5.

t5 can handle most corals in most tanks. There may be a few that really require MH, and MH can make certain corals color up nicer than t5's, but basically they can manage almost anything. Also bulbs last a lot longer than CF and t8/vho, and cost about half that of a MH system to run.

ontheairship... I have 2 of those exact fixtures over a 75 mixed reef with no issues. For the price if you don't like them put it up for sale but I have had these running for 6 months and my tank is fine. I purchased the 20k bulbs a couple of months ago and my algae issues went away.

You have the metal halides? Do you ever have a heat issue with them? That seems to be the first concern whenever I ask someone for advice.

These are some random lights I ran into trying to find the other two lol:

For all those who doubt my future want for "harder" corals I can assure you that I really have a huge love for softies and "beginner" corals. For some reason the more difficult ones just don't do it for me. Weird, I know but my wallet appreciates it!

Thanks to everyone for the advice!

Good news and problem solved! I grabbed some 24"Current Nova Extreme T5's for.....$50 at a LFS going out of business. I also picked up two rocks covered in 180-200 different color zoanthids (mostly green) for $30-$40! I also got a piece of live rock about 5-10 pounds (I'm really bad at estimating) with two groups of flower pot corals for $15. The best buy I have ever made!!! 50¢ blue leg hermits!! Thanks for the help everyone!!
