large chunks of what??? I have LR
as my natural filtration. I do not have tons of debri floating around the tank, the only problem is when my eel and clown get pissed they kick up sand and after a few hours its settled down.
There should not be large chunks of anything in a tank floating around? Not sure what your referring to. I will run filter floss in the sump to polish the water every once in a while. Most sumps have a place to put a carbon bag or floss when needed. In a W/D its a good idea to run the floss all the time to stop waste from collecting in the bioballs. In a sump set up there is not need to run it. If there is any waste it settles out in the tank or sump. the sump I will vacuum out once a year and then there is not that much waste.
The other reason I dont run filter pads is because they trap the pods
and I want them to make it back up into the main tank.
