!!!!??? It's happening again!

ooooh, I see. I think you misunderstood what I did. My reactor is designed to be external or internal. At that point its effluent line was tubing slightly wider than RO tubing, and in the inlet line was a bit larger than that. They're both flexible and a couple feet long.

When I say I took it "offline" I mean that I filled the big Salinity bucket I keep to store spent filter socks with salt water, put a small koralia in it pointed straight up, then put both the effluent and intake line from the reactor in that bucket while I was dosing with chemiclean. The reactor physically stayed in the sump and remained running, it just wasn't using water from the tank. The bucket was well circulated with tons of surface agitation so it shouldn't have gotten anoxic, but yes, for less than a week that it was like that all the organics that sloughed off would have built up in that closed system.

However the salinity bucket is like 7 gallons compared the the reactor's 2 or 3, and when I put it back 'online' with the tank I tossed all the water in the bucket, so 65% of whatever had built up got flushed. If that was enough to kill something, pellets aren't for me anyway.
