I recently purchased a DOC 9010 skimmer. It has been running about 4 weeks and it is producing some skim. I purchased the Foam Extract Unit 9020.140 which Marine Depot said worked with the 9010. I tried inserting the unit in the 9010 and it did not sit all the way down. In looking at the Unit it has ridges on the outside of it that the 9010 cup does not. Will this Unit work with a 9010 and if so how or what do I need to do.
Thanks
