Haha, you people must have not seen my earlier posts on the subject of quieting your bong.

Trust me ... my bong is nearly silent ... I used to use a humidifier filter suspended over the water by cut styrofoam to stop the water dropping noise ... but now I've replaced the filter with a different material that works just as well, but isn't paper-based and won't break down on me. Unfortunately, I'm STILL trying to clean out all the crap that formed due to the humidifier filter. Regardless, its still nearly silent ... and of what little you CAN hear ... its a comfortable white noise, not that low drone or hum of a fan or pump.

As for restricting the system ... as much as I'd like to have kept it at 1/2" it ended up ripping the northbridge mounting points from my motherboard on my previous IS7 ... the tension was so high on my tight-bend turns. I was forced to move down to 3/8" ID Tygon tubing when I added the third waterblock.

Now, thanks for answering the questions on the type of pump I need ... that saved me from a BIG mistake, but does anyone actually have experience with the 30 vs the 20, in noise? I'm hoping both will be like my eheim ... dead silent once the vibration has been cut out. I think the 20 is like that since I've heard some reports as such, but I haven't seen any posts about the 30.

Sound is a sensitive subject ... and I know pumps make different noises than fans and such, but any comparisons would be greatly appreciated. I found that the vibration-induced noise of my eheim 1060 was VERY annoying ... so I isolated that ... but I haven't had much experience with the noises that a pump's motor will make .... since the eheim is silent in that respect. All vibrations aside ... do the Iwaki MD20RLZ or MD30RLZ have a considerable motor noise? What could it be compared to?

Thanks!
