No. They are not kidney shaped and are larger. These are extremely small, no
eye spot would be possible to see with a light microscope etc.
I'm not saying what they are yet. I would be guessing if I did.

Send me a sample. Many Desmids tend to be larger. I have a good 1000X and a
1200X light scope.
It's difficult to tell what many are. A fair amount is involved and
sometimes you have to grow the algae and watch it's development to assess
what it is and you might be an order off. That's a job.

NH4. Even a little is all it takes. Healthy plants with enough "food" do
great at removal, but if they are stopped from growing by low CO2, NO3, PO4
etc, this uptake will also stop, O2 production will decrease, less O2 to the
