    Membrane based aquarium dialysis

    I am doing training to learn about peritoneal dialysis, which uses diffusion across a membrane to remove waste products from people with kidney failure. Has anyone heard of using a membrane and freshly mixed saltwater to remove nitrogen/replenish trace elements this way?
