I don't understand... We'd end up with fish diseases? The idea is to
treat the fish wastewater with hydroponically grown plants, not human
wastewater. John, what modifications would you suggest?
On board my 53' biobarge I treat small amounts of human sewage
biologically in a series of 22 tanks. Almost no pathogens make it through
my 'marshland' tanks (hydroponically grown spartina).
