I am thinking of moving to a t5 hybrid for my 180. With black Friday around the corner, trying to get people's thoughts. I think a 2 bulb t5 will be more than enough for the 180 and help provide a little more fill light, currently unable to grow plants under the java fern. I am going to keep my planted plus 24/7 on the tank in 24/7 mode so I have a longer viewing window. Anyone have bulb suggestions, was looking at one geiseman tropic and one superflora. Planned fixture will probably be a 60" reefbrite retrofit, although I am considering 2x36".
