I am planning a build closely resembling the triton method. I know the "manual" says not to use filter socks, but I don't quite understand all of the reasoning. Is the idea that the detritus and food particles actually land on the algae and rocks in the refugium which serves a particular purpose, or could I have a detritus settling area in front of the refugium where the heavier detritus mostly settles out of the water and then release neutrients into the water to feed the refugium? I think I saw a post saying that the idea is to actually have the detritus land on the algae and into the actual refugium section, but why? Isn't it a huge pain to have to clean out the detritus after it builds up, or does the refugium never really need cleaned for some reason?
