I have aquarium indoors and ponds outside.
In my outside pond there's an external filter with a lever on the top. Flipping that lever and the direction of flow is reversed and all the muck from the filter goes into a bucket that I pore on my garden. I still do a proper clean of the filter every so often but that back-flush once a week keeps the dregs out without disturbing the ecology in there.
But I've never seen a reversible aquarium filter. Does such a thing exist?
