2 x Eheim 2217 (1000 l/h - 260 gph each), 1 x standard internal juwel "jumbo" filter (the black thing in the back on the right side) (1200 l/h - 300 gph I believe) all with Eheim substrate pro.
1 x Eheim 2252 internal with foam cleaned out every other day.
1-2 50% water change every week.
I tried to hide as most of the ugly green hoses as possible, so I put them in the internal "jumbo" filter.
