So no socks, no skimmer. I’m guessing that any extra coral foods will make it to the sump and get eaten up by bacteria and micro cleanup crews on the LR. I’m not planning on any fish in here so most bio load would come from overfeeding. I have a few pounds of live rock in my display sump I planned to move over, maybe I’ll just keep seeding more in there since the tank is pretty well established. Or just buy a few pounds and get on with things.
I like this idea, especially since my sump is a 20g deep. I can extend the dividers and put live rock, bricks, rings and all kinds of good habitat in there. Nice idea.
