Ok, so put it simply there are two processes going on with the fish urine (mainly ammonia):

1, NH4 to NO3 (done by nitrifying bacteria)

2, NO3 to peptides/proteins (done by algae and certain bacteria)

Without algae, the situation may be like:
NH4= 10ppm
NO3= 10ppm

So the NO3 "neutralize" NH4 and resulting in pH 5 -7.

With algae, the situation may be like:
NH4= 10ppm
NO3= 1ppm

The NH4 concentration is still the same (10ppm) but because NO3 is lower so the pH is raised above 8.

I think we should add more nitrifying bacteria to "green water" to lower the pH.
