bcotton,
Isn't it a misnomer to say the fish poo is growing your plants? Isn't it more likely the ammonia primarily given off by the gills and the subsequent nitrates as a result of the nitrification cycle? Also the various minerals that are made available via mineralization? I mean after all we try and remove the solids don't we and they can actually be harmful to the plant roots.
Not trying to be nitpicky. Just asking.
