In the 150 I have an 8" tang, a 4" trigger, 100 heads of euphyllia, branching type. No sand. I've had it set up for a couple weeks now, and have only had to change out the 4" sock once.
I'm only turning over the tank volume 1/hour. That will make a big difference.
I used an old acrylic sump I had laying around, so that's all I had room for.
