My issue with feeding fish to fish is that I have forty to fifty different stocks which are never intermingled. None ever come in contact with another stock or the water from another stock. If a new pathogen should appear, it would be confined to one group which could then be treated or destroyed without jeopardizing the others. If BSF can be shown to not be a vactor for bacteria or virus of concern, then I'm comfortable with it. I have a small challenge experiment in mind.
I decided to use a very modest ventilation system which runs off an existing air blower used to aerate fish ponds. Basically just a few airline tubes under a false bottom in the bin. The air should turn over in the bin about every fifteen minutes.
So far, all the materials have come off a pile of scraps from other projects. My wife's been hinting that I should haul all that stuff to the dump so it's time again to make something useful from it and buy the pile of junk another six months.
