Mag Drive 5 Pump Noise

[bededog]

I posted this in the New Hobbyist forum earlier. I really need some advice on this so I am posting it here too.
I set up a refugium yesterday with PVC plumbing to and from the display. The fuge is in a closet behind the wall that is behind my display. I turned the MAG 5 pump on today and it seems very loud. I knew I didn't want very much flow through the fuge so I set it up so the out flow went through a four way conecter. Basically the four ways are 1) From the pump 2) to the fuge and the other two are just pipes with holes drilled in them for use as spary bars.
The only thing that I can think of that might be causing the excessive noise is my PVC pipes go through the wall (sheet rock only). I drilled the holes in the wall just big enough so that I could just push the pipes through. I think that the tight fit of the pipes are the reason for the loud vibration noise.
Please, If anyone has any ideas I would appreciate some help. I would really like to get this done tonight. I have a fuge critter package coming on Friday.
Thanks in advance.

styro foam, it cuts easily if you heat up a cheese cutter blade with a small torch/propane bottle. It makes a pretty good vibe damper.

I would recomend pipe insulation for where it goes through the wall if thats your problem. they make a foam rubber type that works extreamly well and no mess like the fiberglass

I also have a mag 5.My wet-dry sump is a tight fit with the mag 5 and skimmer.The mag 5 touches the side of the sump and make a noise due to vibration but i cant move it due to size of sump.Mabey the contact of your pump to the wall of your sump is causeing the noise like mine does.

It may very well be the vibration from the wall, but also consider the amount of 'head' that is on the suction of the pump. If there is too little pressure, you may have some cavitation.
Are there any bubbles? That would be a sure sign of it.
