Hey Hulley, so I just setup my H160 on a little refugium under my Red Sea 250 and I'm struggling to get chaeto to grow. I saw you run yours 12 hours at 65-75%, what spectrum do you have it set on, "Grow"? Thanks. Wish I could get growth like that.
Yep, I have the dial pointed at the "W" on the word grow, doesn't look as purple as in the pic but that's where I've had it set.
