fuge?...... no... algae turf scrubber?... yes. Im not a big fan of wet dry filters in fresh or salt water. too much maintenance in the long run to keep them detritus free. With fresh water I prefer poret foam for bio and mech filtration and turf scrubbers for nutrient export (if you cant grow plants for whatever reason). I've had several styles of tank setups and have also learned alot setting up and maintaining aquariums for several businesses. In the end, I've learned to keep things simple and effective. As few moving parts as possible. so my sumps are very simple and effective in both fresh and salt water. for saltwater, I run a skimmer and an algae turf scrubber. for freshwater, I run poret foam and an algae turf scrubber (or grow plants in the DT, not a fuge) very effective, relatively cheap, and super easy to maintain. once you have a sump with poret foam you will never go back to a PITA canister filter or wet dry. (in regards to freshwater) Poret foam is like the protein skimmer of freshwater, I will never set up another tank without one. Super easy and effective. Clean it 2-3 times a year and your done. For my 65g planted freshwater, I'm simply running a 10 gallon tank with 2 sheets of poret foam in it for bio and mech filtration. Could not be happier....... wish I would have done this 6 years ago.
