lighting for macro

[kribbz]

how intense does the lighting have to be to grow macro algae. can anyone tell me

If my memory serves me right, you have metal halides. Macro will grow like crazy under Halides. If you want some Kyle, arrange a time to stop by, I will give you some.

i would like to put some in my sump because i've tried it in my main tank and the tangs ate through it in a day.

I would use at least PC lights. One of those LOA 75W wouold probably work pretty good. Macro algae does need a lot of light. Maybe a 75W MH.

has anyone tried those compact fluorecent daylight bulbs for algae?

TIA

Even a 4000K bulb should work good for algae. I would get a 75W PC, 5000K 6500K whatever, you're not growing corals just algae and 'pods. It should work great.
