dolphin brand air pump - experience?
    #3436428 - 12/02/04 10:35 AM (12 years, 7 months ago)

I've noticed that Dolphin brand air pumps, made by Won Brothers, can be purchased rather inexpensively online. Specifically, the 5-star model, putting out 540 liters/hour, goes for about $25+s/h. I know that Magash has recommended the less powerful 1-star version. Has anyone tried this particular model? The price seems too good to be true.

I see plenty of cheap air pumps, but I'm not convinced that they are powerful enough for the job. Magash's PMP tek suggests 2-3 air exchanges per hour (taken from Stamets?) On a 30gallon tank, it would take a damn load of those $10 pumps to have that kind of output - the $20 pump I have that claims to do 5500cc/min really does only half of that when tested in optimal conditions (ie - not even under water), so I'd need 2 of those. 30 gallons exchanged 2-3 times per hour requires 230-345 liters/hour. That's a hell of a lot of output. I've yet to see anything for $10 that can handle that, but if you've got it - what brand/model is it?
