I believe its one of these:
36" Permeable Flexible Air Stone - EZ Hydroponics & Organics
On another note - do the totes need to be so deep? seems like you will have a hard time getting the lids on with how they are bulging out. Also - perhaps to help the temps you could add some insulation over the concrete walls (behind the mirrors)? otherwise GREAT JOB! I'm getting ready to start my first DIY hydro setup and I love seeing pics of others projects!
