I am re-posting this again to get hopefully some more ideas. I have been using a Pellet reactor for years with outstanding results. One constant maintenance issue is having to clean out the reactor of broken down Pellet. After about a week to 10 days I get a build up of what appears to be a string like slime (kind of like pasta) that is clearly the remains of the pellet. I am wondering if this is normal. From other posting it doesn't seem like it is normal. Most mentioned the need to top off the pellet when they get depleted and disappear. My certainly don't disappear they just create this slimy mess at the top of the reactor( see picture). Then after about 6 weeks I have to tear down the reactor as this slime starts to clog up the bottom plate. I am wondering if there is anything I have setup wrong (to little flow, to much flow, wrong kind of Biopellet) I use NPX Bio Pellet. Could the type of Pellet be the caused or the rotational speed in the reactor. It not a big deal to clean but it would be nice if it didn't happen. Any comments are welcome (like your experience) and if you haven't seen this problem what Pellet are you using. My next step is to play around with different pellet and see if that helps. Thanks all in advance for the comments/recommendation.
