So I added a pencil urchin

I can see where it stays with the lights on, but have yet to find evidence of his work when lights are out. So not exactly sure what its doing.

My black Rock and brown pincushion urchins leave a path of very clean rock.

I got a pencil urchin from ReefCleaners. Best I can tell, it eats the coraline paint off the CaribSea Liferocks. Never seen it touch algae. So, I added a tuxedo urchin. It mostly does acrobatics on the glass and the wavemaker power cord. So got some turbos, and they mostly hung out in the corner. So, I drained down the water 75% and started pulling and scrubbing.

WOW, so I guess I may have to get a stronger brush to get this green turf off. I can pull some of it, but not much.

You probably already know this but pencil urchins aren't reef safe...sorry if I'm telling you something you already know. I'd just hate for you to have a tank full of coral and not be aware of that.

Reefcleaners - they are considered reef safe

I think that's very debatable...they're omnivores and if you do a quick Google search, some people have had them eat corals...i really don't think they're 100% reef safe based on the experiences of others...

Guess if I have a problem, it will end up in the refugium.
