You should be proud. I got into the hobby in April and the learning curve is very steep.

 

Anyway back to your original question, I have a 55 G Frag tank and just installed a 4 tube T5HO fixture over it. I found that for my LPS and softies this fixture had too much light while my SPS did great. I use an AquaticLife fixture with 3 built in timers 1 timer for each 2 tubes and one for the Moon Lights. What I have done is create a dawn to dusk effect by having 2 tubs come on in the morning then around 11:00 all 4 tubs come on until 2:00 PM when the first set goes off  and finally the last set goes off at 8:00 pm. This has given my SPS plenty of intense light while not bleaching out the LPS and softies.

 

The control you get with T5's is great and I would recommend them especially for a tank your size.

 

Thanks, the frag tank is 24"wx60"lx12"h.  and approx 75g. 

Here is a pic I just took with my cell...It's not the best but you can see how its changed

 

I also found that algae was much easier to control when hermits and snails could easily climb onto the frags sitting on the sand. They cannot do that when the frags are up on an eggcrate shelf. Two other things that I found were benefits of placing frags on the sand was that I could use every square inch of the tank bottom and that I didn't have to go fishing for frags that had fallen underneath a rack full of coral.

 

If you are serious about growing coral for cash then you will find it much easier to lose the 55 and do a shallow tank. The pic posted earlier doesn't really show the entire tank. I need to resize some of the pics I have....later.

 

Oh and I used the drain water and a Poormans Wavemaker to create alternating flow in that tank. One powerhead was all it took. I was intent on making money, not spending it.
