I was wanting to set up a refugium in my 28 gal. JBJ reef. Has anyone had any luck with the JBJ Nano Glo LED? I read on another post you need the red,blue lights. Can you change out the Glo Leds if you need the other colors? Or should I just go with a up flow algae turf scrubber in the back section. I don't have room for a sump.:cry: Any ideas will be welcome. Thanks for your enterest and help.:bigsmile:
