Large Matter Filtration

[Gizmo]

What do you use for large matter filtration? (floaties, detrius, stirred up crud) This has been a sticking point for me. I've tried filter sock, but the flow is too great and it overflows instantly. The height of the main tanks and the sump don't allow me to "trickle" drain onto foam pads. I've been considering a Ehiem or Fluval canister to clean out this stuff, but I'm leary about creating a Nitrate factory. - Thanks!
