I have used it several times, and I agree with your friend.  It is a good
source of nitrogen, and it shouldn't be toxic to the fish except at high
levels.  A recommended dosage could be 1 cc of 1 molar urea per three or
four liters of water.  I would wait several weeks before adding more.  It
should have very little effect on the water chemistry.
