Because you are limited in space, I don’t see macro serving your needs. Chaeto reactors and ATS come to mind for limited spaces. In both of those situations you are doing nutrient export. I prefer to do nutrient recycling with pods eating biofilms inside of sump compartment and then letting pods feed the tank.
Aside from utilizing a space what was your purpose for the refugium?
