What Kind of media do you use in your sump?

[mark]

LR rubble and I'm also rotating filter socks on the overflow pipes.

By the way, nothing wrong with a DSB in the sump without a light.

I'm a heavy nutrient feeder so I use:
A skimmer (empty and clean cup once or twice a week)
R.D.S.B. (no light, no maintenance)
Refugium (24/7 lighting, thin macro algae occasionally, flip snails right side up every day or two)
Very little maintenance in total

R.D.S.B. (no light, no maintenance)

Rock, Dead Sand.. and... is this what you mean?

I think it means "Real Deep Sand Bed" but I could be wrong.
