Algaegrower, since you deal with this alot, can you tell us how we can tell which bacteria additive will work and which won't work when we can't even find out from the label what bacteria it is?

I'd love to read literature where a controlled trial is set up to test one bacteria concentrant against another and see how the results stack up. I'm so confused with all the claims about 'warm water bacteria' vs cold water bacteria and how to sort through all the hype.
