    How did you come to your conclusion SM. Experiment with different air pumps and visually estimate from the amount of bubbles or some type air measurement tool.

    And is this the minimum air per inch/cfm..

    Yes, experiment. Taller screens probably need more.

    Can you talk more about these experiments? How many tanks tested? How were the experiment/s performed?

    How do you measure flow of an air pump? Is it supposed to be quoted on the package with other specs? Or is therenany way to measure?

    Is usually printed on the pump.

    You can hold a gallon or liter bottle upside down underwater, and see how long it takes to fill with air.

    Ok cool...is there a problem if the flow is MORE than this? Or is this the minimum recommendation?

    More is better, but is harder to control the bubbles in the tank.

    SM I keep hearing about bubbles in the tank being bad...not to go OT or anything but are they any danger or is it just an aesthetic thing?

    Bubble will hurt sponges and irritate some SW fish. I don't know of any harm in FW.
