I have similar stuff. It seems, in the one tank where I have it,
to be associated with higher iron (and possibly other trace element)
concentrations. This is also the tank into which plant tabs were placed
quite a while ago. I suspect there is still more phosphate there than
is ideal. It does not seem to be related to the nitrate concentration,
in that changes from <1 ppm to about 8ppm do not make any discernible
difference.

If I don't do something about mine occasionally, the water surface
is taken over by 2m long leaves. They are indeed beautiful, but nothing
else gets much light.
