New User to ATI Powermodules

[karliefish]

I am also strongly considering the ATI Powermodules but having a hard time setttling on which size (model) to purchase. My tank will be 300 gallons. The dimmensions will be: 96"L x 30"W x 25"H. So my question is will a 60" Powermodule be sufficient or should I go with two 48" Powermodule and hang them end-to-end? Also, since the 8 ATI Bulb configuration is only 20" wide I was thinking of putting some Kessil"˜s on each sides to cover (may three) the 5" on each side that is left uncovered by the Powermodule. If I end-up using Kessil's on the sides, should I just get the ATI lighting that is all T5's? What does everyone think

I would use 2 48" units end-to-end. The 60" unit is not dimmable. An 8 feet long tank is at least .5" thick which leaves 29" inside at most. You don't want to put corals next to the edges, so there is even less width to cover. If you really want more, Reefbrite units mount directly to the ATI fixture. You probably only want to add a pair in front.
