I dunno man. That's a sketchy theory and sand bed disruption shouldn't put a dent in the "overkill filtration" you told us about. I don't think your tank is cycled completely. How long has this system been running with a bioload, and what kind of filtration do you have? do you have a skimmer?
Moreover, how is your octopus doing? any more stringy tissue coming off? The increase in activity seems like a good sign to me.
BTW, I misspoke about a properly cycled tank not having a nitrate level...nitrate does build up over time.
GOOD LUCK! Cheers, Jimbo
