Serotonin, you say Daylight for the T5, is this 6500k bulb? If so replace that one with a 10k or higher. That would be one reason why the breakout. Also did you lessen the amount of flow in the tank?
Side note I added a refug to my 29 sump with 3" of sand and macro. Within 2 weeks i had great marco growth but also a big break out of Cyano in the refuge area only which was odd since I only added Live sand. I am thinking that the sand had something that made the break out. So went right to the Chemi-Clean to take care of it. |
