    Does not matter the area. Only matters the width.

    Do you run the air continuously like the water flow...or run it periodically like the lighting ?

    I'm not sure if there's a chart table with this information, but I thought I'd contribute to the community since I was looking for it. According to, http://answers.tetra-fish.com/answer.../questions.htm, a Whisper 60 does 2.6 lpm which is good up to a ~7.5 in, and a Whisper 100 does 3.3 lpm which is good up to 10 in. I'm assuming this is when you tee both outputs to one input.

    Hope that helps someone. Maybe there could be a sticky dedicated to pumps and ratings??

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

    Not many tests. Just mine. So the numbers are open for adjustment. But I'm sure that more will be better.

    Hmm, more is better. Got me thinking. What would happen if you built a scrubber screen inside a protein skimmer? Mine produces extremely fine foam. I could build a screen insert and place it down in the skimmer. Place lights around the skimmer. Bubbles surround the screen on all sides and if there are any proteins left then they drift up to the collection cup for disposal. Kind of like a skimmer/scrubber combo...

    Well that's been thought of but I've not seen it built yet.

    Fine bubbles would not penetrate the growth as well, however.

    Sorta tried that with a seaclone skimmer but wasn't satisfied with the results. I pulled the plug and came up with an in-sump overflow instead that is working like a charm. In fact, I'm building an led array for it right now !
