Wow looking great, it won't be long now. You are doing an awesome job.
EDIT: I'm not certain what the streaks are, but they could be staining perhaps from something added previously, or from the algae, or perhaps the lighting or a reflection in the pic itself? Do you see them in the day time? Have you attempted to scrub them with your brush to see if they will come off with some friction? Perhaps others can be of more help and be able to tell you how to rid your pool of them if the brushing doesn't get rid of them. I hope this helps.
