We get our water straight from a filtered ocean tap, so I did a 1/3 change, but he is just getting worse. He is no longer moving, even when food is right by him...though he did try to reach out for my hand when I put it in there. Big bummer, he'll be dead my morning. I think I'll go cry now.
The biggest pitfall of being a responsible Octo keeper is the death of the octo despite best intentions. Sorry to hear about all this.
IMO, nitrates are best kept low by macroalgae (sump/refuge), water changes, and deep sand beds. I used chemicals as a new tank keeper decades ago, but never a good idea for long term at all IMO.
