I just put about 34 LB of live rock in my 55 gal tank 4 days ago and one rock has this green alge growing on it....its green and fuzzy.Almost looks like short hair.....my lighting is two 65 watt actinic and two 65 watt 10000K.Water parameters are fine.Ive only kept fish only tanks in the future and never added live rock......need to know if this alge is okay or if it will overpower the coraline thats already there......it seems to be only on the rocks no where else right now......is this something I might want to keep?....Thank for the help!
