When to pull the plug/restart?

I agree. Test your parameters. Maybe your salt is imbalanced and it threw things out of balance, or at least changed them quickly enough to PO everything on top of the possible chemical contamination.

Are you running carbon? If not, maybe do it for a week or so ...

I'm lazy.

I'd run carbon, maybe some Chemi Pure.

If you don't know for sure what got in there, it's tough to do much more than try a blanket solution.

If that doesn't work, how hard is it really to redo a nano?

You probably have a stash of new sand and LR (don't we all).

Then again, this comes from a guy who never feeds or does water changes.

So?

so it still sucks. I'll likely remove the sandbed at some point. I don't have any replacement sand, that was the last of my stash. My 180 is bare bottom because I can't seem to do sandbeds. I do have some other rock but the pieces are ugly yellow and I don't know if they'll fit in.

I am running carbon, some of those chemi-pure nano thingies. I think I have the full on chemi pure in there right now, or maybe one of the elite ones. I can't remember.

I've decided to give it another month or so. I'll keep up with the waterchanges and such but if things haven't turned around by then, the sandbed goes and I'll replace the rock. Hopefully I can last that long, it drives me nuts looking at it all day, just staring back at me all empty
