Hello everyone, I have had an octopus for the past few months, but the little guy kept hiding in the live rock. Now, 4 months later, My nitrates went from being at 0-5 to being 80-160 within a week, could this be because of a decaying octopus? I dont have any other explanations, as we always clean the filters and skimmer regularly, and do routine water changes. If that IS what it is, how do I remove the body from the live rock so that I can still use the tank for other fish? Right now we are taking each rock out, letting it soak in brand new water, then testing the nitrates to see which is the highest, but are not having much luck. Does anyone else have any ideas besides breaking each rock open? That would really ruin my tank and make it look bad, but if there is no other way, I will do that. Thank you for your help!
