All compost tea production is a brewing process that extracts microorganisms from compost followed by microbial growth and multiplication. This includes beneficial bacteria, fungi, protozoa, and nematodes.

Start with a material that is tested to contain sufficient starter quantities of what you are looking for. Brewing is simple extraction into aerated water to prevent anaerobic activity, and multiplication of the organisms you are looking for.

Not too big a deal if you are just looking to brew quantities for daily use which has a limited shelf life.

Minimum Standards for Compost Tea, per Milli-Liter of Compost Tea

10-150 g active bacteria
150-300 g total bacteria
2-10 g active fungi
5-20 g total fungi
1,000 flagellates
1,000 amoebas
20-50 ciliates
2-10 beneficial nematodes

The information you have posted is correct. There are other brewer makers out there too that also provide large scale brewer. However, you cannot even afford a brewing tank for $100. How could you build an entire compost tea brewer for under $100 that can brew 500 gallons. If you've figured that out, you've cornered the market! Are your test results posted anywhere? Are they above or within the ranges you stated above?
