I have recently made a compost tea brewer and brewed several batches. I am curious as to just what microbes I am growing and how many. I will find a microscope. Is there a good site with pictures that I will help me identify what I am seeing?

You can check the SoilFoodWeb.com.

Better than that, just do a regular Google search or a Google image search, on soil microbiology.

You should get plenty of info and photos and illustrations about aerobic bacteria, fungi, actinomycetes, protozoa, algae, etc.

Most aerated compost teas have different blends and combinations of aerobic bacteria, fungi, and algae. It totally depends on your brewing batch ingredients, climate, weather, aeration, etc.

Happy Gardening!
