Air Stone??

Hi everybody :)
I was looking at the " Do it yourself " section here at the forum and got interested in that Humidifier .

My question is: What is a" Air stone "? I´m from Sweden and asked my local petshop-owner, but he could´n help, so I put my faith in you guys :)

May the force be with you all

Hope this helps: Petco's air stones and diffusers.

Thanx Maria
Now I know
:)

You're welcome, but now I'm curious what they're called there. ;)

i went to petco and bought it its called an air stone in NY

so what do you do with it? i mist have missed that thread. can someone redirect me?

It's a part for the DIY humidifier.

do you have to have it? whats it for?

It helps when you are having trouble keeping your humidity at the proper levels. If your humidity is acceptable, then there's no reason to use it.

oh, i think you misinterpereted me, my bad i should have been clearer, i ment the airstone

It bubbles the water in the DIY humidifier thus making more of it airborne. It also helps to push air into the bottle which pushes the humid air out of it.
