IMO, and IME, if you have adequate flow in your tank, you will get this detritus build-up in your diplay. When I had my 16g bow, I didnt have enough flow and always had to vacuum the crap out. Now that I have my 20L with manilfold, I get zero detritus build-up. I have almost 700 GPH going...
If you dont have actinic supplementation, or you prefer a bluer look (which generally leads to more fluorescence from the corals) then don't hesitate going with the Phoenix. I just got a 150 watt phoenix about a week ago and I dont think will ever use any other brand.... the color is AWESOME...
Have you checked out the PAR on 15,000k lamps? Even on a 250 watter, you are generally lookin at a PAR of just over 50 PPFD. You can get almost that much (~47 PPFD) out of a 150 watt 20,000k Radium.
Just thought I should point that out.
