I have a used sea side aquatics cs1 skimmer. I believe its called cs7 now. Anyway, its under a year old. when I received it I notice it had 3 marks on the cone. Im not sure what from but it didnt effect the skimmer in any way so I kept it. It hasn't giving me any problems. I will attach a photo for oyu to see. Im asking $235 shipped for it.
This is the pic where you can see the 3 marks, looks like hot plastic, just a guess. Also as you can see there are 4 screw things that hold the cone down to the base. 1 of them had the head bust off, I was told you can find a replacement and Lowes for cheap. I haven't been there too look yet.
Again the marks you see do not effect the skimmer in any way.
