This is exactly why I don’t these UGF boxes. They always get clogged up. You can try use a thin layer of sponge between the soil and UGF plate. Also I would fill that UGF to the top with soil. With the thickness of substrate you have in that tank. The UGF isn’t going to do much. All the Asian breeders use UGF with a single grain thickness of substrate.

I'm not going to give up on it yet. I have enough parts to make 3 or 4 more with improved modifications.
