Im in the process of setting up a 180G planted discus tank. Probably going with mostly low light stuff....val, swords, nothing crazy. When i bought the tank i got along with it 3x 250w halides w/ballasts and 1 400w w/ballast. The reflectors were junk so in the garbage they went. My problem is i think with 72" tank running 2 250 wont get me the coverage i need and im sort of up in arms about what to use. Im thinking of selling all the MH stuff and going t5 may be a better idea. But looking for some other input on what may work better.
