    Hey Andy,

    Here's a cast of one of your European perch (Perch fluviatilis) that I assembled and painted as an American yellow perch (Perca  flavescens).

    18 inches (45.72 cm).

      Must be too cold up your way? I've heard of some really big ones in Russian and Eastern Europe.

    Any words of encouragement for nitrites that don't seen to want to go back to zero? 

    The tank was previously cycled, and even when temps were allowed to drop to 18 C. the bacteria did just fine with additions of ammonia on a regular basis. However now at 12 to 13 C.  it keeps creeping up unless I add a nitrite neutralizer twice a day. 

    Do I need to just be patient?

    There is plenty of surface area (4 cubic feet of plastic media) and aeration.

      Nitrites were at zero this morning! Granted I did a 40 percent water change yesterday afternoon, but when I did that before, I still had nitrites the next morning. I'm cautiously optimistic.
       
      I also slowed down the tumbling of the plastic media in the moving bed tank yesterday, started feeding some swim up fry, and stopped adding nitrifying neutralizing compound. Perhaps those were factors?
       
      And or the addition of phosporhic acid is a factor?
       
      I guess the problem with the shotgun approach to solving a problem is you never know which solution solved the problem or if it was all of the above or some of the above. That said I'm cautiously optimistic and don't care as long as the nitrites stay at zero on the API scale!

      Actually load regarding feed was nil until now. Trout alevins were not fed but were living off of their yolk sacs. I am now getting swimming up fry so I'm feeding them small amounts of fry powder about 8 X daily. Still doesn't amount to much. 

      Filter 2/3's full with 4 cubic feet of media. Should be plenty even in cold water. 

      Have been running NACL at about 0.2 percent to protect the fish.  

      Nitrites do rise even with the treatment to about 1.0 mg/l. My concern is that trout are supposed to be more sensitive to nitrites than any other species.
