Forgive my oversight, I didn't mean to imply you hadn't already said the same sort of thing I just wanted to try to elaborate on it. Trying to think of ways to quantify measurements of a skimmers effectiveness. (To be fair, Steve, you did also say "it doesn't sit right with you" so I thought we could to figure out some reasons.... I thought you brought up an interesting topic, I should be allowed to pursue it with you!!!)

For example I am sure we can agree that one such quantification is the rate at which DOC is removed from the water, another might be the efficacy (note this is not a typo for "efficiency") of the foam (i.e., a beckett style has low efficacy compared to a counter-current but makes up for it in terms of volume turnover). What about a minimum threshold? Do think that there can be a minimum threshold of amount of DOC before a skimmer might "start" to be effective or do you think it's closer to a linear relationship?
