are you Running tank with out filter sock

[Madreefer]

I use filter socks in my own tank and dont find that it takes up too much of my time changing them. I look after a 350G tank and wish I could use filter socks on that one. But i'd be there too often as they dont even know how to empty the skimmer cup. I have to vacum out the sump at least once a month due to all the detritus. Filter socks would eliminate alot of that.
