Water Hyacinth Challenge
I bought some water Hyacinth about a month ago, and it seemed to be doing so well. It was multiplying, and eventually filled the upper pond with nice green plants. However now, they are all brown and yellow looking, and I don't have any new growth that I can see. I am using a modified "Skippy filter" design, and the hyacinth is part of the filtration system. The water has cleared up, so the filter appears to be working, it's just the hyacinth that is the problem. What happened? I'm in Southern California.
