For me, its working out so well right now, I can't imagine changing. I see my corals and fish all day long, 6 hours under bright light and about 12 hours under room light (my room is very open and bright most days). My power bills down, no algae or cyano anymore, corals look better than ever. Can't complain.
Ya, 20K really reduces PAR. Just wondering...why wouldn't you use some supplimental actinics, and change to a lower Kelvin on your halides? I would think you would get better growth just based on that as coral growth is increased with lower Kelvin due to photosynthesis increaasing.

For you guys saying you want to see your fish...do you guys stay home all day? Pfff...I don't like you guys anymore. Wish I could do that! Heck, I haven't even seen my home since December...oh wait, I don't even have a home anymore.
