Look up info and recipes from Dr Elaine Ingram and Tim Wilson (AKA Microbeman) they won't steer you wrong. Good tea is simple - all you need is molasses or a similar food source, quality compost, kelp, and maybe some fish hydrolysate. Shouldn't really be more than 3-5 ingredients really. With aerated compost teas, simplicity is where it is at, and less is usually more.
FYI anyone telling you to add guano, bonemeal, or anything like that to tea does not know what the heck they are talking about or understand the basics of what compost tea is or how to make it correctly. You can make nutrient leachates (which should not be confused with tea) in a manner that is similar to making tea, but that is a totally different process with a totally different end result. Tea requires very low nutrient levels for the microbes to grow and thrive, so adding guano or anything else with a higher NPK value is very counter-productive.
