As I indicated in previous message, I have had cases of green water that
could not be completely removed with a diatom. I am pretty sure that there
are some micro, microspopic forms of algae that will pass thru the diatom
filter. I think Chlorella is one example. Dinoflagelattes are much larger
and will be filtered. But your idea of a dye is intriguing... Could the
algae have released its chlorophyll and dyed the water.  Next time I have
this phenomenon I will add carbon to the filter and see what happens. I wish
I had a good microscope <g>
