M Marai75 Feeder Fish MFK Member May 1, 2011 5 0 0 USA May 7, 2011 #1 How long should the blue light t-5 bulb be on? I have just set up a 29 gal SW tank with coral, 2 clown fish, 2 fire fish and a blenny. I have heard that the light need to be on for 4 hour, other people say 8 -12 hours. I don't know what to do.
