Hello Fellow Reefers, I have been trying to get rid of some hair algae growing on tips of acro's , months back I had a bad dino outbreak and it did a number on a few acro's . Since I finally beat the dinos now the tips that were damaged are growing hair algae. I have cut the tips off to remove but keeps coming back. Can someone please give me a few tips to get rid of it. Today I dialed back the red and green channel on radions to see if that will help.
