Alright guys, I can't do no science, but I need some help.

buy a different pump

Suspend it with rubber bands.

>we cannot place anything between the cabinet and the tank
Say what? There should be polyethylene foam or something to spread evenly the weight of the aquarium. If there isn't - you're in for a suprise.

>>8599507
There's something that came pre-installed beneath the aquarium glass already, and the manual /specifically/ says to not place anything between the tank and stand. This does sound like a swell idea, I'm just worried because the manaul says not to and I don't wanna risk it. Not to mention it'd be a risky pain to remove the tank and put it back.

>>8599488
Not sure if I can, everything came pre-installed, as Juwel's usually do. If it's the only possible option I'll look into it though.

There's furniture on either side of the tank, so maybe there's something I could place binding the cabinet structure to the furniture? Again, redirecting the vibration is perfectly acceptable, as well as dampening it altogether.

Get a rubber mat and put it underneath the cabinet

Is the fishtank in the same room as her dad? If so, the best you can do is soundproof curtains. You could still use those anyway and it would solve your problem anyway. Really, that's the only thing I can recommend since I don't know how the rest of that room is layed out, and I doubt you want to post a picture of her house on 4chan.

Place something heavy atop the filter assmebly to dampen it?

Or if its vibration caused by the filter vibrating against the wall of the tank, maybe put little squares of tape on the corners where the plastic meets the glass?

>>8599569
You definitely have my attention. What material would work best if I go with the placing above the filter route?

Also, for the tape idea, I trust you and all, but how does that work? Could little bits of tape really absorb all the vibration? And what type of tape would be best to use, if you know? And would it help if I added it on more than the corners? Sorry for the question ogreload, it's just I'm in a wee bit of a rush. Thank you though, I'm eager to hear more.

You shouldn't have an aquarium on a second story without reinforcing the floor. 60g of water is 600lbs.

>>8599628
It's not 60 gallons my dude, it's 30-something

>>8599634
>Having a tank less than 60g
pleb.

i bet its freshwater, too. you disgust me.

Give me the mass of the tank and the filter's natural frequency and I'll tell you what the spring stiffness should be for the dampening material

>>8599628
>60g of water is 600lbs

What?

>>8599640
He meant G for gallon. Either way, he's wrong. 1 Gallon of water weighs 8.36 pounds, so 60 gal would be 501.6 pounds.

>>8599821
that's just the water not the poly or the wood holding it up

>>8599828
I was only talking about the water, I was just trying to clarify someone's post. Either way, that weight wouldn't be much more than ~20 lb, which just makes about a ~4% difference.

>>8599834
Obviously you've never lifted wood in your life.

You're going to want to suspend it with silicon fibers inside a vacuum chamber. That will cut down the vibrations.

If you put a couple of really powerful lasers inside it then you might even be able to detect some gravitational waves.

>>8599821
>The gauss, abbreviated as G or Gs, is the cgs unit of measurement of magnetic flux density (or "magnetic induction").
Typical /sci/.

>>8600013
It's shorthand and context based, since you wouldn't say you had 60 gauss of water.

>>8599473
what's the distance between the tank and your dad's room? Additionally, if you measure the amount the filter vibrates per second, I can tell you the distance away you should put the tank in order to obtain destructive interference in the vibration waves, which should result in less sound

>>8599838
depends on the kind of wood, if it's just some plywood it'd be light as fuck. if it's solid red oak it'd weigh 30 pounds tops.

Better: use Sorbtane mats.

Rubber is elastic and does not really absorb that much of the vibrations while sorbtane is specifically made to absorb the vibrations and turn this mechanical energy into heat.

This.
Let it vibrate, decouple it from its environment. You cannot dampen away low frequency vibrations.
