Is the algae able to derive carbon from the dissolved organic carbon (DOCs) in the aquarium water?
No, only heterotrophs or mixotrophs can.

why my algae continues to grow strongly but the alkalinity level remains at 125 ppm?
Because CO2 dissolves into the water. Slowly. When a scrubber is growing too fast for this, alk is reduced.

Dosing alk can help the scrubber grow faster.
