Something else I just realized too. My Amazon Swords began developing
yellow/brown areas on many of the leaves and quit growing just about
the time the BGA started taking over. I guess that should have been an
indicator. I'll google those symptoms and see what I find.


So right away you knoe something is wrong with their nutrients.

Ironically crpts can do really well in a tank full of BGA. I've
never figured that out. By really well I mean bigger longer leaves than
when it's cleared up.

BGA is fixes nitrogen so I assume your BGA tank is low on NO3. In a
tank full of BGA, individual BGA cells would be continually dying and
falling to the substrate. Perhaps the crypts find dead BGA a better
nitrogen source than NO3 in the water column.
