This combination does not look good from the standpoint of the phosphoric acid
with the nitrogen.  Phosphoric acid is H3PO4 when the hydronium ions (H+)
break off it will lower the pH of the tank and also leave phosphate anion left
over.  The combination of nitrogen and phosphate would set the algae on a wild
growth spurt.  From my experience I make phosphate the limiting nutrient for
algae so I never add anything with phophate with the exception of the small
amount that I get from my well water.  I also believe that the urea nitrogen
is a precursor for ammonia but am not sure.
