I personally would not worry about detritus at all. As if I chose to use this method, I would be pumping water out of my sump, post filter sock. I would be interested to see the affect this filter would have on ph. I would imagine it having a positive affect. As it would definitely allow a lot of gas exchange as well as introduce more oxygen. I wonder what size it would have to be to be effective. As with any filtration contact time matters a lot. Idk. Just thinking out loud I guess.
