ok i'm upgrading my 150 to a new 400...it will be a full reef with mixed corals in it, in my old tank i had two 60" T5 fixtures with four bulbs a piece...the new tank came with a 60" fixture with 3 MH and 4 PC's...the 60" fixture isnt covering enough of the tank since it is 96" long and 30" wide...i dont plan to run a chiller so i'm thinking is should stick with the T5's, but should i just add two more 24" fixtures so they cover the whole tank or what??
