Hey Dez your corals still look great! Are you still running those LEDs? Since I put up mine I too have been getting some algae on the sandbed. I think it's due to the lights. But after reading what you posted about the flow that might also be a factor. Alot of my corals have grown alot and I dont really seem to get the undertow anymore on the sandbed. Is this hijacking? Sorry if it is.
