You need a minimum 0.05 CFM (cubic feet per minute), open flow of air and an optimum 0.08 CFM per gallon (US) or higher to make aerated compost tea (ACT). ACT should have the DO2 sustained at or above 6 PPM. Generally, aquarium pumps produce around 0.02 to 0.16 CFM. Another generality is that 25 watts of power usually produces 0.75 to 1.0 CFM in diaphragm air pumps. The wattage is usually marked on the pump which will help you figure out the approximate output.
this kind of gets me worriedI'm using an eco air 3 commercial pump. It is rated at 65 liters per minute, I would not go any smaller for an air lift design as it is barely enough to force the tea up and over
this kind of gets me worried
i just built a 5 gal vortex brewer & ordered a eco-plus comercial 1 pump to work the air lifts.was even planning on splitting the air tube into two lines to pump up two 24" pvc pipes both a inch thick....
no this thread is about building tea brewers.
the sticky'd tea article is over here.
ACT is a culture that is used to repopulate your soil's biology.
basically you're taking some very biologically active compost, and putting it in a very sexy environment where all the beneficial microorganisms get it on and reproduce like crazy. then you pour that all over your (well amended) soil and the little buggers go to work breaking down organic material and insoluble nutrients and turning them into plant food.

will drop a PM when i get the pump & try to fire her up...Dark old boy, I think you can run an airlift fine with the ECO 1 pump. Have you already got your piping? Don't go any larger than 1.25" pipe but 1" may be better. When you are ready to blast drop me a PM or email (he is an old OFC friend) and I'll give you a hand.
Don't use the damn threaded brass fitting that comes with the pump. You need tubing that goes over the nipple/protrusion otherwise you won't have enuf air volume.
Edit: Duh! ya you already got yer pipe.
Calm down son!i used the eco 1 based off your website recommendations and the same with cumming up with this design..you personally have helped me a whole lot with out really knowing.
thanx bud!!
My idea with the 15 gallon tanks is to create another affordable brewer for market. (gotta eat).
I need this brewer....where can I find it?
I really want to support somebody on this website, but it looks like I might just have to make it myself. O well.
