I would recommend 175's or 250's. FWIW I use 2x250's on my 55 gal
. One thing I would warn you of is the heat. I have a 15 gal
sump attached to my tank, and in the summer the water temps can get hot fast(even w/ AC
in the house). 175's would cut the heat some and probably work close too, if not just as well on this size tank.
any good deals on a 2 x 250 mh system in the 14k range as well.
I got CoralVue 250w MH
retro kit w/ electronic ballasts for under $190 each including lamps.
