Converting from reef to fish only
I currently have a good 200 lbs of live rock with a 3" sand bed and for my filtration I have two sumps. In the first sump I have two socks where the water drains in to then trough the first sump with some live rock and a skimmer then in to the scound sump that is filled with live rock as well. My question is, if I want to get rid of the LR in the show tank do I need to add bio balls? If so can I add those in to the filter socks? Or can I leave it the way it is with LR in both sumps only?
