What is this algae on my dwarf hairgrass, and how do I get rid of it? Will my nerites or amanos eat it? Will it be bad for the grass if I cut it all super short? Do I even need to remove it or will it just go away on its own as healthy grass grows in? It's mostly on the melting blades, but there are a lot of melting blades because my CO2 and lights were out for 5 days.

Looks like Hair algae. Its not going to show up if your lights were off though. It’s typically a Co2 issue and most likely too much light. Remove what you can and increase co2 and decrease light intensity.
