It wouldn't be hard to get useful data, and to make it seem like folks are asking for the world is just exaggeration. A simple before and after measurement or picture would be very helpful. That isn't what is generally being posted to show effects. Growth over time doesn't really show anything if you do not know the growth without bubbling. All one needs to show is what exactly changed with bubbling. That is the only way one can evaluate whether the method is useful and how it compares to other methods trying to accomplish the same thing (like aeration by skimmer vs aeration by bubbles).
Ok so have any of the community members setup 2 identical tanks including all filtration and lighting to start testing or are they still either asking for the people that have gone through the trouble of testing this on their systems to either
A. Let their tanks go to crap for a little, then start scrubbing to see the results.
B. Setup 2 more tanks to prove that what they are doing on their DT works?
And ill be 100% with you, with the way some people are arguing about it, even that wouldn't be enough.
