I did a 72 hour black out on a tank to get rid of a bad hair /thread algae problem. It got rid of of most of the algae. There was however still some left. I had to turn the lights back on because of some very demanding plants were starting to fade fast. I was just wondering if the left over algae will come back or is it dead and just hasn't fell off. Anyone with black out experience let me know.
