Can someone please help me figure out how to get rid of this algae problem! Looks like green hair algae but not sure. Tank is over two years old and been battling this algae for over a year. It’s grows from all the crevices in my rocks. Nothing will touch it… not tangs, fox face, lawnmower blenny, snails, urchins, even a sea hare or mollies. I also have hermit and emeralds. I have been pulling out what I can weekly but it’s really stuck in at the base. So maybe briopsis? Reef flux killed most of it twice but it grew back in a week each time. My nitrates were higher at the time but right now phosphates are reading only .02 and nitrates around 10. Was thinking of trying reef flux again. Maybe two rounds. I am thinking the issue may be fueled by me feeding my copperband a little neck clam from the grocery store every other day. Idk. Here are some pics… any suggestions greatly appreciated.
