Maybe you want to do a bit more regular water change for now, reduce lighting or break your lighting hours into 2 (eg 8am - 12pm, 6pm - 10pm). See if it helps get rid of those hair algae.
I ever gotten very bad green hair algae bloom due to excessive lighting (3 days 24hrs) as i forgotten to off it (before i use timer). The whole take was just covered! Can't recall exactly how I got rid of it, but if I don't remember wrongly, lighting was one.
