In setting up a new tank, I plan on using a 150 gallon Rubbermaid stock tank full of rock and rubble (which I already have aging in another stock tank), a skimmer, maybe a Red Sea Reefmat and an external refugium plumbed into the system. I started thinking – is this overkill? Does is make sense to use rock/algae and refugia for biological filtration along with a skimmer and fleece roller? I want Pods but those already live in my rubble.
The rocks and rubble stay along with a skimmer but do I really need both a fleece roller and refugia or just one of them or neither of them to keep life simpler?
