I have a small 10 year old Tetra Wisper air pump that I keep just in case my main one dies. It will only run one air stone but it's so quiet that you cant even hear run. but now they've changed them so I have no idea if the new one are as quiet but I'd give them a try.
I found a quiet air pump,
it is called a fusion, quiet power
it is a nice white and grey and i have never heard a sound from it, i have the meduim size with two out ports and can dial the air pressure,
I do believe it is the best one i have ever purchased and not a bad price
the pump comes in i do believe 5 different sizes
No-no. That's obvious, of course, there is noise from the water bubbles. I'm talking about the pump itself. If you just plug it in (stand alone), is it possible for it to be so quiet such that you don't realize it is on.
Yes they are, Wem use fusions, we even have 5 - 700's running in our bed room, can't hear them. We have 3 runnings in our living room, again can't hear them. My brother in law has another brand that is silent, but I can't remember which one
i have a fusion 500 air pump with like 3 outputs and all...in my room...not a big room...and the air pump is pretty quiet...think the water outta the HOB filter is louder than the airpump..serious..bang for the buck...cuz the are pretty inexpensive think i bought mine at J and L...and i think April's place has them too.
