I have fast flow, I prefer cyperus and water celery for open root (not
potted). INgrid

Ingrid,

What would you recommend for veggie filters?

Our WH grows 12" root systems and 18" tops. Takes a lot of
nutrients! Our water celery also has dense roots and big tops, but
the roots are more of a MASS than those of the wh and thus have less
flow-through filter effect. I am very interested in your preferences.
