will it benefit the freshwater plant species...
No. The blue spectrums are for SW corals. Freshwater plants prefer much lower color temperature. Most of the twin-tube fixtures I see have one 10,000k bulb for the fish & one pinkish bulb for the plants. I dont know the exact CT, but probably in the 4,500K to 6,500K range.
