food do you suppose that algae grows on?

I will assume it grabs the ammonia before it's converted or
immediatly after since I get a zero on Ammonia and nitrite both.
Nitrate stays around 20 ppm (no matter how many plants I've added)
so I assume the plants and whatever algae are in these tanks are
keeping the ammonia down to zero. However I can't stop them from
producing ammonia.

If you put your hand in the gravel and stir it up, right down to the
bottom, what happens?
=========================
Not much since the gravel gets vacuumed with every water change. Some mulm
flies up... then settles back down.
