Best aerator for DWC

May I ask why you're so concerned with concealing the pump noise? Small aquarium pumps don't make much noise at all.

I would think that a submersible air pump would heat up the water in a DWC bucket rather quickly.
 
Thanks for your reply lordjin,
I had not thought about the fact that pump can produce heat ;(
It consume 4W and probably is lost to heat no more than 1 watt that should not be a problem.... i hope.
Otherwise i was considering the pump named "jbl prosilent s100" (http://www.amazon.de/JBL-6450100-ProSilent-Durchl%C3%BCfterpumpe-S-100/dp/B000A216QU/ref=sr_1_1?ie=UTF8&qid=1317072833&sr=8-1). Is external, consume 1,5W and move 60 l/h that are sufficient for a little DWC.
Noise produced is 5db that is very low, but isn't scalable (Hydor can move from 50 to 150l/h).
What do you recommend?

thanks for your time

I would go with the ProSilent external pump. Even if that submersible doesn't put out much heat, running it constantly all day long in a small body of water will eventually heat it up.
 
Ok probably I'll follow your advice ;)
In my opinion with this pump i can use a reservior of (max) 2 gallons.
I know that is necessary a pump that produce 36 l/h each gallon of water.
Is right?

Honestly, I'm not one of those guys who go by 'minimum necessary requirements' for cannabis growing. I know mathematically it's all been figured out what marijuana needs to grow, but when it comes to light and oxygen, more is always better imo.

You'll do fine with that air pump in a two gallon bucket.

Happy growing! :D

I have a 20 gal res with my 5 gal bucket inside.total about 17 gal water.1 double outlet air pump with 2 airstones in bucket,and another 2 outlet pump with 2 air stones for the res.
Walmart-$10.00 a pump.4 watts and never hear a thing.More then enough oxygen for everything.
Not rocket science.
 
check out flooming, all you need need is a very small submersible pump and you could even do it on on/off cycles with a cheapo timer

note: the biggest thing about doing this is you want to get the pump secured in place to the bottom of a res, using a piece of PVC or something solid at the piping.
