I run 2 Marineland C360s and 1 Pro Clear Aquatics 200 Wet Dry system. I use both the C360 for mechanical packed with sponges, poly and some matrix and then the Wet/Dry for bio packed with the usual bio balls and in the sump -- bags and bags of matrix. Tank is crystal clear with little maintance needed on the filters. Lots of choices out there, of course your budget will dictate what you can use in the end. Best of luck.....
