I’m new to this so please forgive me. Can someone explain how the back “sump” on this tank works? After feeding a couple flakes, the remaining food goes through the slots on the back, and I can look at the left most Chamber (which has a mini refugium and bio balls in it, and the food is just doing circles on the top of the surface of the chamber. I have a sicce 2.0 pump, shouldn’t this stuff get pulled down into the next chamber, and then the second chamber. How come it just floats at the top?
