Is your pump waking the dead?
Does it drone on all night like the missis?
AK47
Failing that
Nicker elastic.
There are two things going on here. One, the suspension of the vibrating items, such that they can't transmit any vibration. Partially extended elastic. It can't be near it's elastic limit, or still in it's unstretched state. It must be able to move freely up and down. I have not only my pump on this free standing furniture, but also an extractor. You can put your ear to the wood. It's nothing.
The second, perhaps unseen method, is the bottle reducing the pneumatic pumping action. The pneumatic pump shakes the tank physically without some means or smoothing the flow. PVC pipe was once all we could get, but silicone pipe is cheap and available now, and we shouldn't be cutting costs with PVC. It's the bottle though where the real action happens. I used to just put holes in a lid that the pipes fitted in tightly. Now we can buy these fancy lids aimed at fish tank co2 generation. One pipe stops at the lid, while the other reaches to the far end of the bottle. It can take a good few seconds to pressurise the bottle, but when the air comes, it comes smoother than grease. All tank vibration is gone. We just hear bubbles breaking the surface, like a fizzy drink. You can place the air stone in the bottom, without need to suspend it away from the sides. Presuming you are actually taking that measure already. I have been doing this 30 years, but it doesn't seem common, so thought I would share.
Anyone else have methods? I have thought about balloon bladders, but nothing is as reliable as a plastic bottle. Or is it?
