A question about colloidal silver and the ppm count

Is less more? We were using one that was 10ppm, but I just bought a new one that is 200ppm, assuming that more meant that it would be more effective. However, I just read something online that made it seem like a lower number was better because there is a lower risk of killing good flora.

Help, I'm confused!
