The guy I bought my tank from had a bunch of rock in the sump. It's not
a bad idea if you think about buying dead rock at a bargain and then
allowing it to seed over time. It's not unheard of, but I think most
people prefer the water volume in the refugium.

Usually a sump doesn't have any light, so I wouldn't recommend putting
live rock there unless you want to cook it (ie, kill algae). Refugium
is good because the copepods prefer rock to sand.
