I gotta say Tyler Omand's reply was good!
Ceramic air bubblers ain't gonna cut it. Additionally, bubbling for 30 min is not going to get the intended affect.
The whole point of super-aerating compost is to create aerobic conditions so that the mico-biology multiplies 4x maybe 10x.
I've added a chart of temps and length of aeration.
And here's a link (at bottom) to the most economical system kit I have found. They used to have a 35gal setup kit with everything needed. Looks like they still have the parts for one but they cut out the barrel. My 35 gal set was $300 delivered to the door. You'd be amazed how much tea you actually go through in the garden.
As Tyler mentioned... yeah I'm running mine 24/7. It's a pump used for hydroponics systemes. I have a 70L/min air pump for the 35gal barrel.
Recipes. Each have their own, but this it what I use.
1 lbs worm castings/10 gal water (non chlorinated). The castings I have have basalt rock dust and kelp added, OMRI organic
1/4 C molasses/10 gal water
40 mL liquid calcium acetate/10 gal water (made from ground egg shells and vinegar (1C ground eggshells to 8C 5% vinegar, let sit for 2-3 weeks))
1 t mycelium powder (I found a mix of 17 endo and ecto mycellium )
1.5 t legume inoculate (bac-T)
[edit]: Once brewed for appropriate time, I dilute 1:4 (tea:water) before adding it to garden.
Have fun, but don't be intimidated. It's rather simple, just need the right equipment. As mentioned above, smell it, it should be sweet smelling. If it smells sulfurous, it's gone anaerobic and should be discarded as you're now growing all the bad stuff

[edit]: there's lot's of pics of their 'snake bubblers' at their site. It's essentially a food grade tube that's been formed with lots of holes to sit at the bottom of barrel. They also have plans for sale for 250gal operations.
