| Re: Good Tips and Ideas for Ouroboros Owners The scrim material for the OPV- if you buy some floor polishing pads for electric polishing machines they have a very open weave to allow gas through but no dust. They're much tougher than either sponge or scouring pads. Used in the D5 at each end of the scrubber to stop the lime from coming through. Works a treat without affecting WOB. |
