    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.

    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.

    OKK...for FW every one uses air stones in the tank itself so i dont think there would be any issues...

    for SW, all the fish stores I have seen here have air stones in their tanks (FO with LR in the sumps)...none in coral display tanks though...

    but then I guess, judging by what I have been experiencing with most of them regarding subject matter knowledge (especially when discussing cycling, nitrogen cycle and scrubbers) seems to be close to nil (not that I am an expert mind u...i just happen to read a lot and like to experiment)
