For the cost of the powerhead, I could find a power filter that would do the same thing. For that matter, buy a $4 box filter and put an air pump on it and it would work just the same.
Cool idea, but I just don't see where I'm getting a great amount of benefit.
It's easier to find used powerhead for sale than used HOB filters. I got a powerhead for $10. A used HOB ac or emperor filter would cost me 25-30. This mod worked for me cuz the water is crystal clear. Box filter are poor mechanic filtration. With the maxijet I get 1200g per hour which give the tank over 10x turnover.
HOBs are a dime a dozen around here. I don't even try to sell them, I just give them away. I'm not sure how box filters can be considered poor. If you are comparing, then you should be using the same filter medium. The only benefit would be the turnover. In a small tank, I'm never had an issue removing particulate with air driven filters.

When i make a video, i take into account that not every body has access to everything in the aquarium trade since people all over the world watch these videos.
This was one of MANY filters i have shown how to make... including the ones you suggest and many variations of them.
