WTB Filter Sock - Making a Flatworm Vacumm

[b_james]

Where can I get a filter sock that will attached to a 1.5" pipe? My plan is to create a vacuum by attaching a small length of rigid pipe with the end flattened to increase the inlet velocity to a longer piece of flex pipe that will connect to my overflow pipe to divert all overflow water through the vacuum. Next I will attached a filter sock to the other end of the 1.5" overflow pipe in the sump located in the basement to trap all the flat worms as I attemp to vacuum these guys off my LR and sand. Lastly the filter sock will be disposed.
