Improdigal-san ~ Confucius say "Balance in all things is good."
I'll bet you already knew that, huh? It's interesting to find the balance of how much macroalgae is too much, and how much is too little. I don't know if I've figured it out yet. Mostly I stare at all the life in the refugium and forget to see how much macroalgae is growing. Then one night, the light comes on, and I run over - open the door - and decide I've probably got too much.
