Help identifying algae for riddance

[Gordon Cashmore]

hair algae or byopsis? Everything at zero. Need some help identifying and eradication

 

[Crabs McJones]

Looks like hair algae. Manual removal by hand or scrub with a toothbrush. And then find out where the excess nutrients are coming from. You're testing 0 because the algae is consuming it. Are you using ro/di for water changes? How much are you feeding and what is your light cycle.
