It's about ACT

The reason I mentioned the "rolling boil" thing, is because of this article that I've read, that states, and I quote "Fine bubbles don’t aerate water. It’s the breaking of the surface of the water that gets oxygen into it. So instead of a lightly bubbling compost tea, you should aim for more of a rolling boil, or churning. To achieve this, you may have to play around with a few different air pumps or generative blowers. Some sources suggested using a high-pressure (3.9 psi), high-volume air pump (17 gallons per minute). Avoid using air compressors as they can damage microorganisms."

How to Make Aerated Compost Tea – Mother Earth News

Aerated compost tea contains thousands of beneficial microorganisms that will rehabilitate your soil.

I'm just not sure which size of air pump to grab to achieve this, I don;t want to purchase a $100+ air pump for something designed to aerate 10 to 20 gallons of water at a time lol

I didnt use airstones when I used to make teas, they are impossible to clean and cause biofilm. I have a 793gph Ecoplus Ecoair1 pump, $46 on amazon, should be plenty powerful to aerate 10gallons, especially if you remove the brass barb and use larger tubing that fits over the entire outlet.

I would like to make aerated compost tea, I have a 5 gallon food grade pail. I don't intend to use a bigger pail (for now).

What is the BARE MINIMUM size of air pump that I would need to fully aerate this concoction properly?

You can use a cheapo fish tank pump and an air stone. I bought my first pump for like $10 and have upgraded to something not that much more powerful… 14gph I think it is. Any way a cheap pump is fine but airstones quickly get clogged. Airflow is important when brewing a tea you can bubble more vigorously and add more oxygen which will increase microbial populations faster if you use an air diffuser. Check out red frogs diffuser…really great product been using this for years now never clogs…

Some stones are easy to clean. If you PM me I'll tell you the secret, :bigjoint:
 
You do not need a big pump dude just spend 20 bucks you just need enough bubbles to break the surface tension of the water to keep oxygen in it. Bubbles don't add oxygen it's the popping on the surface that gives oxygen, you don't need it to be boiling over to be effective.
 
I pick a sharp edged piece of chert and lightly scrape after washing or a brass brush. I buy cheap 6” stones, they
last a year or better, giving small bubbles.
