I ve been using aquarium mulm from my 120gal to dilute teas. Keeping an aquarium isn't hard at all as long as you do a little homework (nitrogen cycle) and stock the right fish. Having a plumbed hydro system running entirely off fish waste would be very challenging. I've heard of dual root zone style where you can still supplement nutrients which aren't fish safe as long as they are dosed in primary root zone (no run off means no contamination of tank water).
