What skimmer is better at skimming D than A, B or C? Please come back and tell us when you find it.
Why even post something like that? That is not what I said and amounts to a flip response with nothing but contempt to back it up. Please keep the comments in context. It will help everybody involved.
If you read the post in context to the comments, you will see that the first example (and your comments) show that the skimemr with the nasty collection cup is the winner. No test needed.
If you are going to try to beat me up, please do rember what your base premise here is. You can't have it both ways
Also, you use "US" like this is me against a thread full of people. I urge you to read the posts again, there are several opinions being floated and refined. Furthermore, several of the folks you keep citing are not in full agreement with each other nor would they be with with your logic.
As for skimming wet, Anthony Calfo is fond of stating that wet skimming is good at removing particulate matter (i.e., compound A). Both dry and wet skimmers are better at removing compound A than compound D.
Nobody said any differently. I responded to YOUR proposed logic. You have not commented on that and have instead tried to change the topic.
As proof, observe current skimmers. All can remove surface scum (compound A). Few, if any, can remove chromophoric dissolved organic matter (CDOM).
What in the world does that prove? Again, nobody said that they would not remove A, B, C, or D. The question regards in what order and/or concentration those compounds are skimmed and how to formulate a reliable test to indicate such.
It is one thing to use the "simple" model to represent the ideas. In reality we are talking about a large number of proteins and a complex interaction the skimmer between the many compounds and the few lucky bubbles that take them to the skimmer neck and hold them long enough to let them overflow.
Again, please post the brand and model of the skimmer that can skim CDOM (compound D). Then pour oil in the tank and let me know which is skimmed first: the oil slick or the Gelbstoff.
Your responses are starting become rather silly, but I think you know that. I had expected a much more intellectual response that was directed towards my comments and ideas. Fishbulb, Hahn, et al. certainly articulated their feelings and ideas without silly examples that have no bearing on the conversation.
Bottom line:
Truth tables are like computers. Garbage in, garbage out. It is the assumptions that are flawed. The scientific method requires testable hypotheses.
The irony is that you will not consider that fact that your assumptions may be what are flawed. You have not used the scientific process and instead are using postulate to argue your points as fact. What you posted with regard to Compounds A, B, C, and D just does not pass the most basic test of logic. You suggest that my logic is garbage, yet where is the proof that yours is not?
May I remind you that YOU proposed the logic... garbage in? And then used those assumptions to form your opinion... garbage out?
You are promoting them [your assumptions] as scientific fact to back up your premise. You have not showed why I am wrong and have actually, unwittingly, reinforced several of my points.
Pour oil in your yellow tank and see what is skimmed first.
Edit: The rest of you don't have to use oil - fish food will do.
Why keep posting things like this? I would ask you to please address my comments and ideas in a kind and respectful manner. If you disagree with my opinions; I welcome informed responses. Please keep the other stuff to yourself.
Bottom line:
I have offered reasoning to show that what you are saying may be flawed. I welcome responses related to what I have said, not snippets of pasted text that misrepresent the ideas put forth. I am more than happy to be wrong, but please show me with sound information or articulated responses. Telling me that Anthony likes wet skimming and oil and proteins will be skimmed at different rates is certainly far from a compelling rebuttal. Comparing a skimmer in a cesspool to a pristine aquarium is silly and asking me to pour oil in my tank is useless if not purposefully inflammatory.
So I pose the question again. If you insist that the skimmer that skims more D will also skim more of everything else, then would the skimmer that had the fullest and foulest cup be the one that is the clear winner? You have stated that the collection cup is not a good indicator of skimmer performance. We have come full circle and as I have pointed out, many of your comments contradict your own base premise in this thread.
