light recommendation to grow macro algae

[bcjm]

My refugium is about 20"x10" area in the sump. The micro algae in it never grows well. I am using a 65W power compact light. I think the light is not strong enough. What do you think?

I've used this lamp, or similar.

what's the "color" of your 65w PC light? I think I'm using a 6500K light and the chaeto is doing great.

Same here 65w pc 6500K. Chaeto and caulpera grows really well.

There must be something else wrong then. Myabe I don't feed the refugium enough water.

I have 2 20 watt Halogens and my cheato grows like crazy BUT the halogens burn very hot.

Maybe there is something else keeping the macros from growing. If your water is nutrient-poor, the macros will suffer.
