Lighting for Macro algea growth?

[Salt4Us]

How much lighting do you need for macro algea growth & support?

We have a 29gal tank with:
40lbs LS
31lbs LR
55W PC Actinic
55W 10,000K PC bright white
BakPak2R skimmer
various corals, snails, hermit crabs & fish (will list these if needed).

We also added CPR's hang on the back Refugium (small) w/ about 1 lb LS & some peices of LR (that feel off the original LR due to movement/placing it). For lighting on the refugium we have JBJ clip on PC (18W 50/50). My wife posted a pic of the refuge on another posting.

Thanks for your help & opinions

I dont know what the minimum light for it is . Perhaps anenomeman can tell you that, but I do know I have successfully grown it under pc lighting.

Already did. John's fishing for a second opinion (don't blame him).

You have plenty of light for good macro algae growth. In either the fuge...or the tank.
