hello everyone. ive setup my first saltwater aquarium and im amazed with the hobby. its been 6 weeks and i have 3 fishes in my aquarium. the problem started when the power was cut off for 3 hours in my vicinity. this brown algae started after that. every day it grows and now its even on my aquascape. can anyone help me with what it is and how to take care of it if it is a problem? @vetteguy53081
