I have to say, I absolutely hate cleaning my waterfall filter media,
which is why it gets done less than it should. It originally had 3 2"
pads and 6 heavy net bags of rocks, and I've since gone to 1 pad,
throwaway net bags of barley straw, and 6 heavy net bags of rocks.
Even that's a hassle though. The mats are just a pain to clean when
they're that size and all those rocks are... well, heavy.

I keep wishing I could convert the bucket into some kind of veggie
filter, but I think the flow rate is too high since it's the output of
3 pumps.
