Lighting: I have a 25.5" x 4.5" x 12" HOB refugium with excellent Chaeto growth ( harvest about 1/2 to 2/3 every month). For lighting I use 2x 23w Panasonic GenIV 5000K bulbs in a "standard" dual incandescent aquarium hood. I modified the hood by putting in a reflector I picked up from Ahsupply.com. All told, it cost me about $40 for the whole works. After putting in the reflector, I got much better growth. The bulbs are good for about 14 - 16 months, when I was running them 24/7. I've switched to having the HOB on at the same time as the main lights, with the sump/refugium on reverse. When I first got the bulbs, they were $14.99 at a local light store, last time, same store, the price had dropped to $11.99, and according to the merchant, prices will continue to drop. IME, this is also a nice light if you want to do a planted FW or marine macro algae nano tank.
