OK.... heres the solution. in the middle sit some kinda urn thing and thread a hose
from a very small slow pump up thru the center (be sure the pump can pump that high.
IN THE URN put water celery and cyperus (papyrus) and water cress and anything else
does well BARE ROOT in water. let the water burble up thru the roots and flow over
the edge, but once the roots get established it will clean up the water. be sure the
hose is really tight in the hole or sealed with silicone so the water doesnt leak out
before it goes thru the roots and over the edge. Ingrid

nasty being algae growth, water clarity gets bad.
Unfortunately, I travel alot and Im not able to maintain the pond as
much as I probably should.
Is there something that I could do to maintain good quality, without
constant supervision?
