I need help. I have had this tank setup for a year now and I am not able to grow any coraline. All I get is this red crap all over my rocks. For lighting im using 4xT5 fixture with ATI bulbs. How can I fight this red algea so I can grow some fancy coraline?View attachment 5697View attachment 5698
The coraline on this power head is from the tank it was in previously.
