Very nice! Looks to be posing or was it a hard photo to get?
Very sneaky!
When is the competition deadline and judging dates?
That is a nice, localized approach. I used to stir things up in a similar manner then relied on the filter to clear up the water. What I was really doing was moving the waste from tank to filter but not removing it from the system. This works if you change the mechanical portion of the filter frequently.
BTW - What video app are you using?
Here is is a video how I reduce organic waste in the aquarium beside a lots of shrimps and a filter with 10x turnover. I use a turkey baster combined with an hose and try to do this biweekly. Works pretty good.
