hornwort won't grow

Thanks for the on and off-list replies.  The hornwort I have
experimented with typically is left floating and tends to slowly turn
brown and loose leaves.  Pretty much the same thing with the
egeria/anacharis.  I'm going to experiment a bit with some
supplemental dosing and monitoring and see what happens.
