See, it sounds kind of gross (though ducks habitually swim in water filled with their own crap), but no one has so much as peed in this thing for probably two or three months. We still flush it every week or so, but no poop, no piss, no chemicals. You could probably drink out of it if you wanted to (I don't).
So, I could let a couple three ducklings swim in it for a bit and once they're fished out to be dried, we could just flush the duck-poo away.
