need help with lighting

perky · 02/28/2007, 12:42 PM

hi guys

in the next few months I will be setting up a new tank (after sitting around tankless for nearly a year). it will be about 75g, give or take measuring 48"L x 20"h x 18"W.

I was looking at getting an arcadia 36" T5 unit with 2 marine blue and 2 marine white @ 14000K.

I was wondering if this amount on light would be beneficial to sps and corals kept near the surface.

thanks in advance

If those are the 36w(?) sets, I would go with a 6 bulb set. Do they have the individual reflectors? If not I would also go with those. The output with ind reflectors would allow you to keep anything you wanted anywhere in the tank. With the 6 bulb set up, you can stagger 2 sets of 3 bulbs to cover the entire width of the 48".

BTW, why not use a 6 bulb set of 48" instead?

the cost is the biggest factor
