I'm not sure which algae it is. It's pretty well set in. My lights run 7 hours a day with a 4 hour split. I don't dose liquid but have root tabs. Since the root tabs I've noticed the algae to be more prominent in the tank. It doesn't just come off with my fingers or when I siphon.
The hygro doesn't look that bad. I've just trimmed it back completely because the growth is crazy. Trying to give lower leaves more light.
