Ahh for about 4-5 months. I dont have all my water parameters, kind of just go by the old eyeball method. I do have temp, varies between 78-80, lighting: 150w mh about 6 inches above the tank, tank is 18 inches deep. I use reef crystals and do a approx 25% water change every sunday. Flow has been an issue in my tank, if anything is it possible that this guy get to much flow? I know that as of lately dealing with cyano, my birdsnest has been getting harmmered by my mp-10.
