The plant growing out of the tank on the left looks like Hygrophila angustafolia to me. I have some growing out of my 90G that looks identical except my leaves are a bit narrower. Is that the one you are trying to ID? Got no idea on the other one running the length of the tank.
BlueGreen Algae usually occurs if the nitrates are way too low and is treated by using an aquatic erythromycin antibiotic such as Mardel's Maracyn. I've had that algae once before and it is nasty stuff. Good luck.
