On my 220 am having a sump setup. I used to run 2 SunSun 304 series on my earlier 125. In my sump I have almost 5-6 times more bio media, and power consumption almost half of 125 setup. Almost silent operation too.
Using 100 micron Filter Socks in sump, for mechanical filtration keeps my water clean as possible.
