I bought this open brain one week ago and I am seeing tissue recession from the 3 oclock to 5 oclock position in the last couple days. He is located in the center of the tank in the sand. Today it seems to be spreading in toward the center area a little bit. Is there anything I should be doing besides just watching? Hopefully this is not brown algae infection? Bleaching?
Param: 1.025, 8.0, Nitrite/Nitrate/AMN 0, Alk 4.3, Ca 375. I am bringing the Ca up over the next couple days by increasing my dosing.
Lighting: 4 T5s individual reflectors
