I have no idea what the algae is... I've seen it before when I let hornwort
or anacharis get too thick, and food and detritus gets kinda stuck
inbetween, and even more so in the hairs. It seems to fertilize itself that
way and only gets worse as it goes along. Perhaps it would be best to do a
heavy duty trim? When I see that type of algae show up, I do a trim,
significant water change, and then refertilize like it was brand new with
Florena or Flourish... whatever. Seems to get the system back in the right
The other thought I've had is... Perhaps all the ions and nitrification
products are unmeasurable because they're getting converted so quickly by
the plants and algae? A lot of people who, as an example, use tap water in
their marine tanks, have hair algae as thick as a fine maidens head, and
swear up and down they can't measure any PO4 until they actually test it
*before* it goes into the tank :) You've *obviously* removed it with the DI
(might also want to check the conductivity of your output water to see if
the DI is getting old)...
However, if there's that much detritus rotting down inbetween the plants...
That's a great source of PO4. Something to chew on.
