I have a home made 150w DE pendant over my 20 gal with a Ushio 10000k bulb in it. I'm very happy with this setup so far aside from the colour I get out of it. The bulb has become much more white now that I am getting close to 100 hours on it but my zoas and my lionfish both look pretty bleh under it. I'm going to put a crocea in this tank so I'm thinking that moving to a 14000k or higher bulb would not be terribly smart unless I track down a radium or something and build different fixture. Most of the other bulbs sacrifice too much PAR.
This leads me to thinking about actinics but I can't figure out a way to do it. The pendant is rectangular about 10" by 8" suspended right over the center. I tried to find a way to get a T5 strip across the back but it was getting too hot because of the MH. I am now thinking about putting a couple of PC strips running front to back on either side of the pendant. I only have a 1' to work with so I can probably only fit 13w bulbs there. I can't decide if this is worth trying or if I am not going to have enough blue coming from them to matter.
So does anyone have some ideas or am I going to have to go back to Albert and get an Aquaconnect bulb? I don't want to see his I told you so dance again
