I have a Nano ReefCasa Studio 12 gallon which I love because it’s more lagoon style. Biggest problem is the filter chamber is about 3x3 and I’d love to get an auto fleece roller but I cant find any that would fit. The filter floss starts clogging in a day and a half which is fine but I need to travel a lot lately so I’ve been using a small piece of porous sponge filter at the back so that if it clogs it’ll go through the sponge. Otherwise it drops the water level in my sump and my ato starts diluting my saltwater. Any ideas?
