Ran my lights on my algea scrubber for 12 hours on reverse time with tank lights and ran my nutrients into the ground . Yep, double 0's dinos showed up and I have been battling them for seems like ever. But, I bubble scubbed the tank and used a soft bottle brush to remove what dinos I could see . The bubbles carry them down the overflows to the filter . I did install a uv light . I scrubbed the tank twice then went with 3 day black out. Everything survived! But, dinos on my 4 week with out dinos but now it's green hair algea.
