Cool DIY Tom. Has it improved the performance of the skimmer. I had a very long debate with the guy from reef dynamics about bubble plates on another forum . He is not an advocate of bubble plates and states they're just a sales gimmick just like cone skimmers. He claims his personal research proved it ??? What was the results of your research ? FYI reef dynamics and euro are the same,he changed the name when he bought it. Very interested in your results. Will be following along !
