New Sump - Refugium or Not

[cjrudy]

So I am building a new sump (40G) and relocating it to the basement. My current tank is doing well so i just figured I wouldn't change anything, current sump is 30G:

Skimmer >Return>Refugium

The fuge has chaeto and some live rock, the chaeto has ok growth but has slowed over the past year and the fuge has started to develop black looking algae.

I also run GA and GFO

So do I keep the refugium in the new sump or not. What else would I use the space for.

I have extra space in my sump and was thinking about adding a bunch of rubble for pods to populate for some mandarins.

I've done both, had a refugium and had a section for all live rock. Both did well, but I rather have a refugium, just to have a place to put certain bully fish in "time out".
