It also depends a lot on the bioload of each individual system. At least we went to the trouble to qualify our experience with some photos. Commenting on the so called lack of skimmate produced by air diffuser skimmers without providing some pictures of new tech skimmers performance doesn't make for a useful contribution to this thread, particularly from someone whose signature block contains a comment about being under a hair algae attack. To be honest, I have some hair algae issues too, but I don't think it's due to my skimmer, it's more likely the unkown history of my used live rock and getting better with each water change.
