macro grow light

[Fishward]

hey, just wondering if anyone can comment on the min specs for a decent macro-algae grow light. have a dsb in my sump and want to light it and put in some chaeto. what kinda wattage does macro need to grow?

I used a basic light dome from Home Depot with a very good grow light.

I don't use it anymore. If you want it, you can have it. Rather see it go to good use rather than just sit in my pile of unused stuff.

Let me know.
