Does anyone know the gallons/minute/gallon airflow requirement for fishtanks?

I was at the fish store looking at air pumps, and I noticed that none of them gave the actual gpm/lpm for the pump, they only called out the aquarium size they were meant for (ie, 10 gal tank or 40 gal tank etc).

I would like to make a comparison of price/performance on the pumps at the fish store versus the grow-store.

I already bought a Wisper 100 (100 gallon size) from Tetra (at the fish store). It kicks the crap out of my eco plus 2 with WAY less noise. I would just like to know how much of the $45 price tag was for output and how much was for quietness. The quietness rules though, oddly, the whisper sounds louder than the eco when you stand right next to it, but the vibration simply doesn't travel outside the room. The eco actually seems louder downstairs from the grow than in the actual cab, while the whisper is completely undetectable outside the cab.

Anyone,

I can't be the only one trying to buy air pumps at the fish store. Seriously, none of the 3 brands of pump at the fish store listed gpm/lpm. But they seem much nicer than the eco plus crap from the grow store.

If it's not listed on the pump anywhere (like on the bottom where all the spec's and listing info are), then you can probably find it at the manuf. site.

Don't buy anything at the grow store that you can buy anywhere else; it usually cost a lot more and doesn't work as well, IME anyway.

thats not true, just opinion.....i actualy find the opposite, there just hella expensive. example, a 172 MM/200cfm a/c axial fan is about 12$ at my local electric store, 60 at the h-store.

i actualy use a fish tank air pump also... i went with a 40 gal pump, it has 2 outputs, i think its a tetra also. it has a rubber base with intigrated rubber cones as "feet" it was about 40$ aswell....
i never actualy looked at the quantity of air they put out, its not going to matter much, unless you have a big, HOT res. somthing is better then nothing.
noise was always more of a concern to me, this pump i have is old though and its starting to make more and more noise. god help me if i put it on a solid surface. sounds like the whole house is vibrating.

That's why I said "usually" and "In My Experience", by no means did I even imply it as a true/false-fact.

Apparently you way overpay at the fish store too:

I paid $45 for this:

$19 doh!

still no specs, though, I'll see If I can find specs for a comparable product.

Still a sweet pump though.

So I finally found a brand of air pump that lists tank size and lpm. This was a 55 gallon size that pumped 9.2 lpm.

That gives me a conversion of .16 liters per minute per gallon for FISH TANKS. So if there is any consistency in the industry, my whisper 100 (gal) is pumping about 16 lpm, that crushes the eco 2's 4.5 and the noise is barely audible.

So I guess I figured it out on my own, j

thanks for the replies though.

You're probably not going to find any meaningful or consistent information on air pumps and related aquarium size. At least not like you would for water pumps. That's because air pumps can be used for many different things in a fish tank. How big of a pump you need depends on what you use it for. For example, I have two fish tanks and don't even use a single air pump for any reason. Unless you are a beginner and use one to run an undergravel filter, or you like seeing bubbles floating up in your tank, or you have a homemade protein skimmer, there's really no reason to use one. (And before anybody says something, air bubbles rising through water don't aerate the water, surface agitation does.)

paid 29$ for a whisper air pump says upto 60 gals has 2 air outlets which are both connected to my 1 gal clone bubbler lol. if ya have the dual port pump dont block off 1 side if it isnt being used, it makes more noise this way. i hooked both ports to a T for my bubbler both hoses run to same bubbler hella bubbles in there my cuts get High off the oxygen being produced. i had 1 side blocked off then was suggested not to it dosent make hardly any noise now. but yrs ago i had 5 diff fish tanks all fresh water some where for feeder gold fish 1 was for babies convicts 1 had allagator gar in it and 150 gal full of african and so american chiclids <-- spell lmao. i had this 1 type of air pum was like a volcano shape that made no noise wish i could remember the name srry. i had 30 fish in the 150 gal had 4 power heads hooked upto the undergravel filters and 3 air pumps hooked to misc things. i had large 2ft tire track eel 18 inch reed fish or snake fish as some call it and many others jack dempsy convicts breedn pair. all non comunity fish but got along fine in my tank i needed the extra oxygen produced
for supplies like that air pumps for resivors or bubblers and such good ole fish supply store cant be beat. they have everything ya could prolly need and cheaper then local hydro store
