Your gonna want a commercial pump for all 10 buckets, or use 10x the power and run 10 pumps, but silent on an air pump your not going to get unless you go with 1 pump per 1 or 2 buckets.

I have a 4 bucket system and use a commercial 40LPM 6 valve pump, now you can get a 10 port valve for these (or two 6's) and run all your pumps. It's far from silent, and it does vibrate a bit. I paid $45 or $49 for mine from a hydro shop, but I got one on ebay this past week for $13 plus $13 shipping that's a 35LPM (40 watts) So you can pick them up fairly resonably, but like I said, unless your going with multiple whisper pumps, your going to have some noise. Mine is sitting 2 rooms away, roughly 15 feet, and I can hear the hum, in the room it's loud, but you get used to it.

You can mount them on rubber feet which helps. When I move (less than a month now) I'll be mounting it to a plastic shelf using rubber feet, and the plastic shelf will be mounted as well using rubber feet. This SHOULD help keep the vibration down, but I'll still be able to hear the pump. I'm sure you can build custom housing for it if you want to, I don't really care about this for my use, but the vibration honestly is worse than the noise (or a large contributing factor to it)

Also, if your running 10 buckets, why a DWC and not an RDWC? I run 4 buckets in an RDWC and I couldn't imagine doing the swap out without my controller bucket
low_rdr Reviewed by low_rdr on . DWC AIR PUMP Question: Greetings, I have buckets and lids for a 10 (5) gallon DWC or ( eventually ) an under current DWC. I'll be starting out with 10 buckets and thru either human or natural error, I'll probably end up with 4 or 5 female buckets. QUESTION: What's the right size air pump ? Rating: 5
