What would be the cost of putting four T5 HO on your tank vs. a dual 250 W MH?
You might consider dual MH and make both VHO actinic's, even if it were another $100+
This would make it a perfect reef. but that's me.
I guess I ought to comment that the T5 do not appear to me to put out more light than VHO. Relative to their actual diameter, perhaps they are more efficient, using less electricity per lumen, but I've seen them and they are not brighter; are not emmitting more lumens than same length VHO tubes. I believe Jon posted some numbers that confirm this.
Since they are still a new product in the hobby, I don't know about their life expectancy and output degradation.
BTW - The coral mentioned above will all grow fine under the current lighting. The Frogspawn would need to be at the top of the pile though. Here is an example. This 180 has four 4 foot VHO and two 4 foot NO Fluorescent. Thats about the same, maybe just a little more than your 135. And that said, I can see why the addition of these T5's is of interest, if they are truly longer lasting and more energy efficient than VHO's.
In addition to the soft coral and gorgonia visible in this pic there are SPS (acropora, pocilipora, and scroll coral) and LPS (bubble coral).
