Ok, I probably should have been a little clearer. I meant, how long
before I really start to notice a difference in the algae. (I think I'm
seeing a difference today, but not sure.) Bryan

Every pond is different. pH can play a part, if it is too high or too low,
water hyacinth can't take up the nutrients as well (and sometimes not at
all, thus they fail to thrive.) ~ jan
