![]() I am considering building a new sump for my 90 gallon. I would like to add a refugium.Also baffles for a bubble trap. I notice many sumps with refugiums dont use a filter sock. Is it necessary to have a filter sock. Or is it better or worse? Any ideas would be great. I will also be using an in sump skimmer
