Hey everyone, I just got a link from Paul Shanahan ("Paultergeist") on an experiment he ran, it is exactly the type of thing I was asking for earlier in this thread. Here it the link:

Great stuff!!! This is exactly the types of experiments we should be doing as a community. And hey, think about all the time and effort that we spend building new filters on some new theory, but realistically we like building filters for our ponds -- doing experiments like Paultergeist's can be just as fun!
Please go read his experiment thread, and think about what you would do different, and consider starting your own controlled experiment. And keep it mind that it doesn't matter if multiple people run the same experiment, because if the results are the same, they confirm each other. If the results are different, then it sheds light on variables that might not have been considered.
I have been stuck on thinking big tanks that I never considered easy small ones -- I've got 2 empty 55 gallon barrels out back that I might make good experiment tanks. Maybe run one with a K1 filter like I use, and the other with an MP2C Cermedia Marine Pure stone things. Although I have a feeling those will instantly clog up making the centers un-inhabitable for the good bacteria, a controlled experiment would yeild real data that other consumers can use when deciding what to use on their ponds.
