Thanks. So flow is all the way up with the 1300 pump that came with it and I have 1/4 of the pellets SICCE claim can be used. I even took the screen out and the pellets do not fluidize like they should. I've reached out to SICCE just waiting to see what they say. Pretty disappointing.
So what you see is the most I've ever seen them move. I set it up with clean water on my counter. These pictures are with the pump on full and without the screen on top.
