Hi all, just wondering has anyone made up a box in which to put an air pump in ,to make it quieter . I tried making one up out of aeroboard but it made very little difference . This set up is in a bedroom so need to do something quickly . Did think or putting a power head on the sponge , but angels in the tank and they dont like big water movement .

Robert, is this a new pump?
Older pumps can get quite noisy when the air filter gets blocked, quite often after this is cleaned and replaced the pump will become appreciable more quiet.
Another reason, I've found is that if the airflow is restricted it will cause the pump to get noisier.
What I mean is if your airline is only going to the one filter and the line is clamped to reduce flow this can cause the problem.
Far better still is to use a tee connector with a valve on the now spare tube to permit the extra air to escape rather than be trapped (I hope this makes sense).
Standing the pump on some foam (sponge) rubber will also help as it will reduce resonance caused by the vibration of the pump.
I don't think enclosing a pump in styrofoam is such a good idea as it might possibly overheat due to the foam's insulative properties. And, if you made it too airtight it would eventually starve the pump of an intake of air.

Many powerheads, thinking about your other suggestion, can have their output reduced quite appreciably so allying one to a sponge filter might well do the trick. While Angels might prefer little flow they are very versatile in this respect and find the areas of least flow.

Just a couple of thoughts there, maybe other members might be able to suggest alternatives for you too..

If it is in the bedroom, do what I did, and put the pump in the loft. Wire a switch on to one of the wires to turn it on and off and run the hose down with it into the bedroom.
Hang the pump off the rafter so it doesn’t touch anything and isn’t on the fiberglass.
Hey presto a quiet fish tank.

A powerhead is the way to go if your tank is in the bedroom.
The aquael pat mini filter heads are bullet proof, cheap and the flow is adjustable to a drip. I have some running my undergravel filters at the minute and used them before to run single and double sponge filters.

Thanks everyone for your ideas, well i went out and brought an ehiem 400 air pump and yes they are almost silent ,but this is the biggest in the range and the output is not great , maybe this is why they are quiet and at almost 50 euro not cheap . My 12 euro chinese pumps have a much bigger output but are noisier

I have the ehiem in my House too very quiet not a huge air flow but I’d be surprised if it wasn’t providing your aquarium with the right amount of air flow it requires

Robert you could try the old school method wrap it in a sock haven't used an air pump in a while but when I did have one on a tank in a bedroom that's what I did.


Or else put it on a sheet of Styrofoam might muffle the sound for you.
