Macro growth looks good!
A few months ago, I got a Lumilite to try out over my smaller sump's refugium. I wanted to see if it would do the job adequately for my customers that buy my sumps. I placed it over the zone, plugged it into the Apex so it would turn on and off daily.
I noticed the macro algae is growing well under this daylight spectrum LED fixture, and I really do like the low profile look of the light.
The legs are adjustable to keep it securely in place, but it's loose enough for me to move it out of my way. I do have to wipe it down because this water level is pretty high, and salt spatter is unavoidable.
This is feather caulerpa, which I grow in both of my refugiums.
