[I]ok, i think i asked this before, but now i am going with a diff tank so want grims, etc opinion..</em>
[I]it is a 6' x 2' x 2' 180g tank. dual back megaoverflows set like 6" away from the sides. i want sps, lps, etc...</em>
[I]i have 2 ic660s with each a 4 48" bulb setup with reflectors now over my 150g.</em>
[I]it is pretty cramped and i have them overlapped/staggered to cover the sides (so down the middle, the lights/reflectors are basically touching, but the ends alternate sides sticking out).</em>
[I]will 8bulbs be enough light for the 180g? what bulbs to get? will the staggering mess anything up? thanks</em>
[I]mike</em>
I'd do 8 80 watt lamps which are 60". Don't mess with staggering them, they will light a 6 foot tank pretty well, You just can't keep high light critters in the last 6 or 8 inches on each side.
[I]thanks for the reply! so i wouldn't be able to drive those with the 660s right?</em>
[I]mike</em>
Sure. Each 660 can drive 3 of the 80n watt lamps, the 430 can drive 2 so 2 660's and 1 430 for the two dusk/dawn lamps.
[I]thanks again for the replys!</em>
[I]so if my 660s are set up now for 4 t5 ho 54w bulbs, do i have to get a new harness or just cut/leave one "group" unconnected?</em>
[I]will i still be able to grow sps as well (in the middle/top of the tank)?</em>
[I]would i still try to use the 8 bulb combo you sent originally for the other tank?</em>
[I]thanks!</em>
[I]mike</em>
I don't remember the exact diagram for 3 lamps but it will be on Ice Cap's web site. You can use the same harness although you might have to extend some wires. Just make good solid connections and it wont be any big deal.
8 lamp mix will be fine but you might have to substitute KZ Fiji Purple for a UVL Actinic White if I suggested those, UVL doesn't make 80 watt lamps

so i guess i can rewire the ic660 that i have now pretty easy it seems..
* does everyone agree that it would be better to go with the -6" off the edges (tank 72", 80w bulbs 60") rather than stagger the 48" 54w bulbs?
*what about using another 660 (so 3 total) to run the other 2 (or even 3) bulbs instead of the ic430?
