    Actually, in a real reef, there probably are more predators (pods) to eat the algae than there are in a scrubber, because algae in the wild is not cleaned every week.

    As for the giant-scrubber example, it would probably do better than a regular-sized scrubber, because the chlorophyll-to-coral ratio would be similar to a real reef. My calculations showed that a regular 100g tank would need a standing stock of at least 4 pounds (remaining after a cleaning) of algae to equal a real reef. The levels of algae/chlorophyll (both benthic and planktonic) on reefs are well-measured and quantified, and the number of corals/gallon on reefs are far less, thus real reefs have a much larger algae-to-coral ratio than tanks do.

    For anyone reading this please be assured that Ace is wrong on the algae dissolved organic carbon issue
    Algae that is being constantly grazed passes its harvested energy rapidly up the food chain which is why coral reefs can support such a high biomass in comparison with other ocean environments.
    Yes when a predator eats the algae some doc may leak out as his highlighted study shows but this is minimal in terms of the overall amounts concerned.
    There is a huge difference between doc being released into the water and algae biomass being consumed and moved up the food chain. Organic and inorganic nutrients are completely different entities.

    OK cam up with the following.
    It would become one instead of 2 screens.
    The screen would be 27x8 which makes 216 SqI which would be sufficient for about 18Cubes of frozen food. ( should do for a 500Gl tank)

    as for flow I was thinking about 1500Gph
    the lighting would be 6 x 23WCFL bulbs on each side so a total of 12 x 23W CFL with reflectors built inside.
    - Would this be enough light and flow
    - was the calculation of the screen size correct?
    please advise as I would like to start design ASAP

    how about the lighting?
    overkill or....?
    and how long should I run them for?
