Ugh Issue Number 19980909 :(
The pump is not working.
I filled the water up to the filtration chambers, switched the black foam with the filter floss, and put the media together in one chamber.
I plugged in the filter and it's making a stutterting sound and nothing is coming in or out. But I do not think it's broken because I felt my hand under into the pump and I can feel the water moving from it.
