It looks like there is a white residue on the inside of the blue bucket just above the water line. Is it residue from something or scratches from scrubbing it? I also have been known to brew some beer. One problem home brewers encounter with fermenting in plastic buckets is that when the plastic gets scratched, bacteria get deep into the scratches and it is impossible to get it out once it has set in. It looks clean and has been sanitized, but every time you start a new batch of beer, it gets contaminated from "who knows where". In brewing, bacteria = bad beer. Only cure is to change out the bucket or switch to more durable material like glass or metal. You may be having a similar contamination problem that will not come out due to microbes deep in the scratches. Just a thought that might help. Change out your buckets n lids?
