What's the egg crate forMine got stuck a couple times also when I sucked up some LR rubble or Nassarius shells.
I cleaned my sandbed regularly, and the water and sand was still just so filthy when I took it out yesterday. I would say I got about 25% of it out, it was so brown it was disgusting.
I have no idea how I am going to take the egg crate out tbh. There is no real way of doing it without tearing the tank down, which isn't really an option.
