My water hyacinth is looking really sick; leaves are turning brown,
plants are definitely in trouble. Ph is perfect, what could the problem be?
Anarchis also does not look good. My marginal plants are doing great, water

Get some Flora Fin, by Tetra... will clear it up the problem. If its a
large pond, do a search here for 'potash'
