  1. I wanted to put a algae scrubber in the overflow area of my AIO tank. the Flow should be more than enough but i am confused if it requires air in order to function correctly.

    Generally if the growth substrate is underwater, you should have bubbles. I've seen it done both ways, without bubbles, the growth is markedly less

    It's a feeding-based guideline

  10. The scrubber is placed at a 45 degree angle in an all in one tank after the first chamber. So water much flow through here. The return pump is rated at 2000/hr. The light is a 7w fixture placed about 2 inches away. The screen size is about 10x5 inches. Any feedback would be great.

    So is that sort of cascading through the screen or is the water flow staying on top? Is there anything under the slanted area of the screen?

    Looks good so far
     
  12. It flow over as to how much not sure.

  13. I need little clarification. In order for this to work to I need to feed 1 cube to the tank with or without the fish eating the food? I ask Cuz my tank is fairly new and have minimal livestock. I don't mine just need to be sure.

  14. Sorry for so many questions but this concept is extremely new to me and most of the research I have read was with established tanks.

    You don't need to feed a tank just to grow algae. I would not. Growth will not be substantial until you have livestock that eat the food and convert it / break it down. Food can decompose in the tank via bacteria but this is not quite the same as waste provided by fish and clean-up crews, etc.

    What you do is adjust the light cycle (photoperiod) so that you are only "on" a couple hours per day, or whatever you need to get a little growth going, or to keep what little growth that you do have alive in order for it to be ready to take off when you do stock the tank.

    Over-lighting the screen with a long photoperiod with no feeding of the tank will result in a bare white screen.
     
  16. So I finally got algae to grow on screen but it was more of a brown algae

    That's actually closer to green, from what I can see. Go easy on the cleaning (harvesting) leave plenty behind, don't scrub the screen clean or anything close to that.
