Clean as a whistle, no scratches. But to be honest, one of the reasons I'm selling it is because it's not as quiet as my other filters. I'm not saying it's loud, just not as quiet as my Eheim or Fluvals.
Cool, if its not to much trouble bring it tommorow an we can talk, Im close to needing a New Impeller for my magnum 350 an the Impeller well on mine has some grooves in it.
Ya the Impellers for those are pretty pricey. I basically use mine for the Micron cartridge only, much cheaper in the long run when you compare it to having to rebuy the filter sleeves for the powerhead quick filters to.
