How often or more precise how much should we harvest from our ATS at any one time? My Atlantis 2 grows algae at a phenomenal rate so much so the screen is well overladen with algae well within 7 days, in fact, I am thinking harvesting every5 days may be more appropriate.Many people clean the screen hard back to the screen as I have often done but I am thinking trimming the algae like a haircut with scissors might be a better option, in fact, I have done both, that is harvested every 5 days and gave the algae a hair cut. My thinking is my water quality would be more stable as removing algae back to the screen would slowly increase nutrient wise until the algae grew back sufficiently to deal with the nutrient build up. Removing say 80% of the algae would leave enough behind to continue to take up nutrients and given I feed a lot and often then this would be no bad thing at all. I have not taken any water tests to prove or otherwise the above however so it's all just theory. Does anybody have any views on this?
