Biopellet reactor spin speed

[Ocelaris]

I have a reef octopus biopellet reactor that has an aquatrance pump on it and the pellets were going around so fast that they got stuck at the top and clogged the screen. I just added a gate valve and now have full control (the pump wouldn't dial back enough with the on-board knob). How fast are we looking to churn these things? Like where they're rubbing themselves off? Or is it just to tumble gently? Thanks
